“I follow no leader but Christ and join in communion with none but your blessedness [Pope Damasus I], that is, with the chair of Peter. I know that this is the rock on which the Church has been built. Whoever eats the Lamb outside this house is profane. Anyone who is not in the ark of Noah will perish when the flood prevails” (Letters 15:2 [A.D. 396]).
“The church here is split into three parts, each eager to seize me for its own…. Meanwhile, I keep crying, ‘He that is joined to the chair of Peter is accepted by me!’ …Therefore, I implore your blessedness [Pope Damasus I] …tell me by letter with whom it is that I should communicate in Syria” (ibid., 16:2).
