St. Columbanus

“For all we Irish, inhabitants of the world’s edge, are disciples of Saints Peter and Paul and of all the disciples who wrote the sacred canon by the Holy Ghost, and we accept nothing outside the evangelical and apostolic teaching; none has been a heretic, none a Judaizer, none a schismatic; but the Catholic Faith, as it was delivered by you first, who are the successors of the holy apostles, is maintained unbroken.” (Epistle 5, to Pope Boniface IV).
