Chapter 16 — Part II: The Sacraments — Baptism
Section 83. Seeing that Baptism should be sought with a view to put on Christ and to be united to Him, it is manifest that he who purposes to continue in sin should justly be repelled from the sacred font, particularly since none of those things which belong to Christ and His Church are to be received in vain, and since we well understand that, as far as regards sanctifying and saving grace, Baptism is received in vain by him who purposes to live according to the flesh, and not according to the spirit. As far, however, as the Sacrament is concerned, if the person who is rightly baptised intends to receive what the Church administers, he without doubt validly receives the Sacrament.
