Apostolic Constitutions, Book III 8

1For how does such a one know of what character the person is from whom she receives? Or from what sort of ministration he supplies her with food, whether it does not arise from rapine or some other ill course of life? While the widow does not remember that if she receives in a way unworthy of God, she must give an account for every one of these things. For neither will the priests at any time receive a free-will offering from such a one, as, suppose, from a rapacious person or from a harlot. For it is written, You shall not covet the goods that are your neighbour's; and, You shall not offer the hire of an harlot to the Lord God. From such as these no offerings ought to be accepted, nor indeed from those that are separated from the Church. Let the widows also be ready to obey the commands given them by their superiors, and let them do according to the appointment of the bishop, being obedient to him as to God; for he that receives from such a one who is worthy of blame, or from one excommunicated, and prays for him, while he purposes to go on in a wicked course, and while he is not willing at any time to repent, holds communion with him in prayer, and grieves Christ, who rejects the unrighteous, and confirms them by means of the unworthy gift, and is defiled with them, not suffering them to come to repentance, so as to fall down before God with lamentation, and pray to Him.
