Public worship is important. It not only makes us unite, but it confounds Satan. Even in time of persecution.
It is better to be righteous than talk about it.
Our lives are our witness. And for Ignatius, his death was part of this.
Take heed, then, often to come together to give thanks to God, and show forth His praise. For when ye assemble frequently in the same place, the powers of Satan are destroyed, and the destruction at which he aims is prevented by the unity of your faith. Nothing is more precious than peace, by which all war, both in heaven and earth, is brought to an end.
None of these things is hid from you, if ye perfectly possess that faith and love towards Christ Jesus which are the beginning and the end of life. For the beginning is faith, and the end is love. Now these two. being inseparably connected together, are of God, while all other things which are requisite for a holy life follow after them. No man [truly] making a profession of faith sinneth; nor does he that possesses love hate any one. The tree is made manifest by its fruit; so those that profess themselves to be Christians shall be recognised by their conduct. For there is not now a demand for mere profession, but that a man be found continuing in the power of faith to the end.
It is better for a man to be silent and be [a Christian], than to talk and not to be one. It is good to teach, if he who speaks also acts. There is then one Teacher, who spake and it was done; while even those things which He did in silence are worthy of the Father. He who possesses the word of Jesus, is truly able to hear even His very silence, that he may be perfect, and may both act as he speaks, and be recognised by his silence. There is nothing which is hid from God, but our very secrets are near to Him. Let us therefore do all things as those who have Him dwelling in us, that we may be His temples, and He may be in us as our God, which indeed He is, and will manifest Himself before our faces. Wherefore we justly love Him.
Ignatius, Epistle to the Ephesians
