"[L]et us consider equally the rites of the priestly supplications which, transmitted by the apostles, are celebrated in the same manner in the entire world and in the whole catholic Church, in such a way that the order of supplication determines the rule of faith [ut legem credendi lex statuat supplicandi]."
+ Prosper of Aquitaine, Capitula coelestini, fourth century (PL 51:209-210)
