Apostolic Constitutions, Book II 61

1But if any one allege the pretence of his own work, and so is a despiser, offering pretences for his sins, let such a one know that the trades of the faithful are works by the by, but the worship of God is their great work. Follow therefore your trades as by the by, for your maintenance, but make the worship of God your main business; as also our Lord said: Labour not for the meat which perishes, but for that which endures unto everlasting life. And again: This is the work of God, that you believe in Him whom He has sent. Endeavour therefore never to leave the Church of God; but if any one overlooks it, and goes either into a polluted temple of the heathens, or into a synagogue of the Jews or heretics, what apology will such a one make to God in the day of judgment, who has forsaken the oracles of the living God, and the living and quickening oracles, such as are able to deliver from eternal punishment, and has gone into a house of demons, or into a synagogue of the murderers of Christ, or the congregation of the wicked?— not hearkening unto him that says: I have hated the congregation of the wicked, and I will not enter with the ungodly. I have not sat with the assembly of vanity, neither will I sit with the ungodly. And again: Blessed is the man that has not walked in the counsel of the ungodly, nor stood in the way of sinners, and has not sat in the seat of the scornful; but his delight is in the law of the Lord, and in His law will he meditate day and night. But you, forsaking the gathering together of the faithful, the Church of God, and His laws, hast respect to those dens of thieves, calling those things holy which He has called profane, and making such things unclean which He has sanctified. And not only so, but you already run after the pomps of the Gentiles, and hasten to their theatres, being desirous to be reckoned one of those that enter into them, and to partake of unseemly, not to say abominable words; not hearkening to Jeremiah, who says, O Lord, I have not sat in their assemblies, for they are scorners; but I was afraid because of Your hand; nor to Job, who speaks in like manner, If I have gone at any time with the scornful; for I shall be weighed in a just balance. But why will you be a partaker of the heathen oracles, which are nothing but dead men declaring by the inspiration of the devil deadly things, and such as tend to subvert the faith, and to draw those that attend to them to polytheism? Therefore, you who attend to the laws of God should esteem those laws more honourable than the necessities of this life, and pay a greater respect to them, and run together to the Church of the Lord, which He has purchased with the blood of Christ, the beloved, the first-born of every creature. For this Church is the daughter of the Highest, which has been in travail of you by the word of grace, and has formed Christ in you, of whom you are made partakers, and thereby become His holy and chosen members, not having spot or wrinkle, or any such thing; but as being holy and unspotted in the faith, you are complete in Him, after the image of God that created you.
