Augustine of Hippo

This whoso hath held fast, hath made no heresy; this whoso hath held fast, hath made no schism. For whence came schisms? When men say, "we" are righteous, when men say, "we" sanctify the unclean, "we" justify the ungodly; "we" ask, "we" obtain. But what saith John? "And if any man sin, we have an advocate with the Father, Jesus Christ the righteous." But some man will say: then do the saints not ask for us? Then do bishops and rulers not ask for the people? Yea, but mark the Scriptures, and see that rulers also commend themselves to the prayers of the people. Thus the apostle saith to the congregation, "Praying withal for us also." The apostle prayeth for the people, the people prayeth for the apostle. We pray for you, brethren: but do ye also pray for us. Let all the members pray one for another, let the Head intercede for all.
