15 That you are desirous, indeed, to be rid of this impiety, I know well; but since each man may not be able easily to accomplish this by himself, let us enter into fraternities and partnerships in this matter; and as the poor do in their feasts, when each one alone would not be able to furnish a complete banquet; when they all meet together, they each bring their contribution to the feast; so also let us act. Inasmuch as we are of ourselves too listless, let us make partnerships with each other, and pledge ourselves to contribute counsel, and admonition, and exhortation, and rebuke and reminiscence, and threatening; in order that from the diligence of each we may all be amended.
For seeing that we observe the affairs of our neighbour more sharply than we do our own, let us be watchful of the safety of others, and commit the guardianship of ourselves to them; and let us engage in this pious rivalry, to the end that thus becoming superior to such an evil habit, we may come with boldness to this holy feast; and be partakers of the holy Sacrifice, with a favourable hope and a good conscience; through the grace and lovingkindness of our Lord Jesus Christ, by whom and with whom, be glory to the Father, with the Holy Spirit, for ever and ever. Amen.
