Examples
“Apostolicae sedi et antiquis ab initio nascentis ecclesiae et catholicis traditionibus tota mentis intentione, tota cordis alacritate, me conjungo.”
The Catholic Encyclopedia, Volume 6: Fathers of the Church-Gregory XI
“When she spoke of “adoptio” by God, or of “participatio dei,” for example, although a spiritual relationship continued to be understood, yet its basis and reality lay in a sacramental renewal of the physical nature: “Non ab initio dii facti sumus; sed primo quidem homines, tunc demum dii” (We were not made gods at first; at first we were men, thereafter we became gods at length).”
The Mission and Expansion of Christianity in the First Three Centuries
“* [1112] Eâ gratiâ fit ab initio fidei suæ homo quicunque Christianus, quâ gratiâ homo ille ab initio factus est Christus”
