1. On The Cathoic Faith

There is indeed one universal church of the faithful, outside of which nobody at all is saved, in which Jesus Christ is both priest and sacrifice. His body and blood are truly contained in the sacrament of the altar under the forms of bread and wine, the bread and wine having been changed in substance, by God’s power, into his body and blood, so that in order to achieve this mystery of unity we receive from God what he received from us. Nobody can effect this sacrament except a priest who has been properly ordained according to the church’s keys, which Jesus Christ himself gave to the apostles and their successors. But the sacrament of baptism is consecrated in water at the invocation of the undivided Trinity — namely Father, Son and holy Spirit — and brings salvation to both children and adults when it is correctly carried out by anyone in the form laid down by the church. If someone falls into sin after having received baptism, he or she can always be restored through true penitence. For not only virgins and the continent but also married persons find favour with God by right faith and good actions and deserve to attain to eternal blessedness.
