John the Baptist calls him the Lamb of God who takes away the world's sins (John 1).
1 John and Hebrews teach he appeared and was offered once to abolish many's sins.
Latin
IV. Quoniam autem Deus tantum beneficium nobis confert per & propter Christum, idcirco dicitur a Joanne Baptista, Agnus Dei qui tollit peccata mundi. Joan. 1. Quo spectat alter Joannes, dum ait in prima epistola, Scitis quia ille apparuit, ut peccata nostra tolleret. Et Apostolus Paulus in epistola ad Hebraeos docens Christum apparuisse sine peccato ad destituitionem, sive abolitionem peccati; & illum semel oblatum fuisse ad exhaurienda, sive tollenda multorum peccata.
