This one is also from Steganographia by Trithemius. I think I pretty much got the first and third parts, but the part in the middle is driving me crazy:
...ipsamque fidem Catholicam secundum traditionem S. Romanae Ecclesiae suscepi a cunabulis, baptizatus in nomine Patris, & Filii, & Spiritus sancti, quam cum ipsa & universali Christianorum Ecclesia teneo, credo, & quam diu vixero, cum Dei auxilio semper inviolata firmiter servans, corde, ore & opere tenebo, nec unquam ab ipsa deviare quacumque occasione intendo.
...and I undertook from childhood the Catholic faith itself according to the tradition of the Roman Catholic Church, baptized in the name of the Father, and of the Son, and of the holy Spirit, with which themselves I support, believe, and live daily by the universal Catholic Church, with the help of God serving always inviolate, I will support with heart, speech, and deed, and never at any time do I intend to stray from themselves for any reason whatsoever.
Any help is appreciated!
