I love the old writers, because they did not have a bone of polticial correctiness in their body. To deny the divinity of Christ is called a detestable blasphemy. Satan is described as pulling our faith out by its roots. They had a better sense of fairness. Consider the schoolmaster on justice:
Dr Briggs suggests we note equality and diversity do not mean now what they meant.
1 Since divine justice requires, for the preservation of equality in things, that punishments be assigned for faults and rewards for good acts, then, if there are degrees in virtuous acts and in sins, as we showed, there must also be degrees among rewards and punishments. Otherwise, equality would not be preserved, that is, if a greater punishment were not given to one who sins more, or a greater reward to one who acts better. Indeed, the same reasoning seems to require different retribution on the basis of the diversity of good and evil, and on the basis of the difference between the good and the better, or between the bad and the worse.

What Calvin calls simple and sober belief is still hard believe. It requires the spirit of God to understand, for we are man, and not God. We argue by analogy, he argues by true knowledge. I commented to a friend that this chapter, at three sections or so a week, is taking most of the COVID 19 crisis to get through. No matter. We can only eat so much meat at once.
20. Let those, then, who love soberness, and are contented with the measure of faith, briefly receive what is useful to be known. It is as follows:–When we profess to believe in one God, by the name God is understood the one simple essence, comprehending three persons or hypostases; and, accordingly, whenever the name of God is used indefinitely, the Son and Spirit, not less than the Father, is meant. But when the Son is joined with the Father, relation comes into view, and so we distinguish between the Persons. But as the Personal subsistence carry an order with them, the principle and origin being in the Father, whenever mention is made of the Father and Son, or of the Father and Spirit together, the name of God is specially given to the Father. In this way the unity of essence is retained, and respect is had to the order, which, however derogates in no respect from the divinity of the Son and Spirit. And surely since we have already seen how the apostles declare the Son of God to have been He whom Moses and the prophets declared to be Jehovah, we must always arrive at a unity of essence. We, therefore, hold it detestable blasphemy to call the Son a different God from the Father, because the simple name God admits not of relation, nor can God, considered in himself, be said to be this or that. Then, that the name Jehovah, taken indefinitely, may be applied to Christ, is clear from the words of Paul, “For this thing I besought the Lord thrice.” After giving the answer, “My grace is sufficient for thee,” he subjoins, “that the power of Christ may rest upon me,” (2 Cor. 12:8, 9). For it is certain that the name of Lord (Kurivo”) is there put for Jehovah, and, therefore, to restrict it to the person of the Mediator were puerile and frivolous, the words being used absolutely, and not with the view of comparing the Father and the Son. And we know that, in accordance with the received usage of the Greeks, the apostles uniformly substitute the word Kurivo” for Jehovah. Not to go far for an example, Paul besought the Lord in the same sense in which Peter quotes the passage of Joel, “Whosoever shall call upon the name of the Lord shall be saved,” (Acts 2:21; Joel 2:28). Where this name is specially applied to the Son, there is a different ground for it, as will be seen in its own place; at present it is sufficient to remember, that Paul, after praying to God absolutely, immediately subjoins the name of Christ. Thus, too, the Spirit is called God absolutely by Christ himself. For nothing prevents us from holding that he is the entire spiritual essence of God, in which are comprehended Father, Son, and Spirit. This is plain from Scripture. For as God is there called a Spirit, so the Holy Spirit also, in so far as he is a hypostasis of the whole essence, is said to be both of God and from God.
21. But since Satan, in order to pluck up our faith by the roots, has always provoked fierce disputes, partly concerning the divine essence of the Son and Spirit, and partly concerning the distinction of persons; since in almost every age he has stirred up impious spirits to vex the orthodox doctors on this head, and is attempting in the present day to kindle a new flame out of the old embers, it will be proper here to dispose of some of these perverse dreams. Hitherto our chief object has been to stretch out our hand for the guidance of such as are disposed to learn, not to war with the stubborn and contentious; but now the truth which was calmly demonstrated must be vindicated from the calumnies of the ungodly. Still, however it will be our principal study to provide a sure footing for those whose ears are open to the word of God. Here, if any where, in considering the hidden mysteries of Scripture, we should speculate soberly and with great moderation, cautiously guarding against allowing either our mind or our tongue to go a step beyond the confines of God’s word. For how can the human minds which has not yet been able to ascertain of what the body of the sun consists, though it is daily presented to the eye, bring down the boundless essence of God to its little measure? Nay, how can it, under its own guidance, penetrate to a knowledge of the substance of God while unable to understand its own? Wherefore, let us willingly leave to God the knowledge of himself. In the words of Hilary (De Trinit. lib. 1), “He alone is a fit witness to himself who is known only by himself.” This knowledge, then, if we would leave to God, we must conceive of him as he has made himself known, and in our inquiries make application to no other quarter than his word. On this subject we have five homilies of Chrysostom against the Anomoei (De Incomprehensit. Dei Natura), in which he endeavoured, but in vain, to check the presumption of the sophists, and curb their garrulity. They showed no more modesty here than they are wont to do in everything else. The very unhappy results of their temerity should be a warning to us to bring more docility than acumen to the discussion of this question, never to attempt to search after God anywhere but in his sacred word, and never to speak or think of him farther than we have it for our guide. But if the distinction of Father, Son, and Spirit, subsisting in the one Godhead (certainly a subject of great difficulty), gives more trouble and annoyance to some intellects than is meet, let us remember that the human mind enters a labyrinth whenever it indulges its curiosity, and thus submit to be guided by the divine oracles, how much soever the mystery may be beyond our reach.
22. It were tedious, and to no purpose toilsome, to form a catalogue of the errors by which, in regard to this branch of doctrine, the purity of the faith has been assailed. The greater part of heretics have with their gross deliriums made a general attack on the glory of God, deeming it enough if they could disturb and shake the unwary. From a few individuals numerous sects have sprung up, some of them rending the divine essence, and others confounding the distinction of Persons. But if we hold, what has already been demonstrated from Scripture, that the essence of the one God, pertaining to the Father, Son, and Spirit, is simple and indivisible, and again, that the Father differs in some special property from the Son, and the Son from the Spirit, the door will be shut against Arius and Sabellius, as well as the other ancient authors of error. But as in our day have arisen certain frantic men, such as Servetus and others, who, by new devices, have thrown every thing into confusion, it may be worthwhile briefly to discuss their fallacies.
The name of Trinity was so much disliked, nay detested, by Servetus, that he charged all whom he called Trinitarians with being Atheists. I say nothing of the insulting terms in which he thought proper to make his charges. The sum of his speculations was, that a threefold Deity is introduced wherever three Persons are said to exist in his essence, and that this Triad was imaginary, inasmuch as it was inconsistent with the unity of God. At the same time, he would have it that the Persons are certain external ideas which do not truly subsist in the Divine essence, but only figure God to us under this or that form: that at first, indeed, there was no distinction in God, because originally the Word was the same as the Spirit, but ever since Christ came forth God of God, another Spirit, also a God, had proceeded from him. But although he sometimes cloaks his absurdities in allegory, as when he says that the eternal Word of God was the Spirit of Christ with God, and the reflection of the idea, likewise that the Spirit was a shadow of Deity, he at last reduces the divinity of both to nothing; maintaining that, according to the mode of distribution, there is a part of God as well in the Son as in the Spirit, just as the same Spirit substantially is a portion of God in us, and also in wood and stone. His absurd babbling concerning the person of the Mediator will be seen in its own place.
The monstrous fiction that a Person is nothing else than a visible appearance of the glory of God, needs not a long refutation. For when John declares that before the world was created the Logos was God (John 1:1), he shows that he was something very different from an idea. But if even then, and from the remotest eternity, that Logos, who was God, was with the Father, and had his own distinct and peculiar glory with the Father (John 17:5), he certainly could not be an external or figurative splendour, but must necessarily have been a hypostasis which dwelt inherently in God himself. But although there is no mention made of the Spirit antecedent to the account of the creation, he is not there introduced as a shadow, but as the essential power of God, where Moses relates that the shapeless mass was unborn by him (Gen. 1:2). It is obvious that the eternal Spirit always existed in God, seeing he cherished and sustained the confused materials of heaven and earth before they possessed order or beauty. Assuredly he could not then be an image or representation of God, as Servetus dreams. But he is elsewhere forced to make a more open disclosure of his impiety when he says, that God by his eternal reason decreeing a Son to himself, in this way assumed a visible appearance. For if this be true, no other Divinity is left to Christ than is implied in his having been ordained a Son by God’s eternal decree. Moreover, those phantoms which Servetus substitutes for the hypostases he so transforms as to make new changes in God. But the most execrable heresy of all is his confounding both the Son and Spirit promiscuously with all the creatures. For he distinctly asserts, that there are parts and partitions in the essence of God, and that every such portion is God. This he does especially when he says, that the spirits of the faithful are co-eternal and consubstantial with God, although he elsewhere assigns a substantial divinity, not only to the soul of man, but to all created things.
