Even if Peter did preach in Rome, as some secular literature from the first and second centuries implies, there is no proof that he was head of the congregation there.
Isegi kui Peetrus kuulutas Roomas, nagu mõned esimese ja teise sajandi ilmalikud allikad vihjavad, ei viita miski sellele, et ta oleks olnud sealse koguduse pea.
