Other Baptisms

Et forte si quis existimet sibi in Sacramento baptismi perfectam illam innocentiae, et coelesti vita dignam redditam puritatem; Joannem Baptistam dixisse recolat, Ego quidem baptizo vos in aqua poenitentiae; qui autem post me venit, fortior me est: ipse vos baptizabit Spiritu sancto, et igni: ipsum autem Dominum baptizatum a Johanne cum adhuc esset in corpore meminerit locutum, Adhuc habeo alio baptismo baptizari. Est ergo, quantum licet existimare, perfectae illius emundatio puritatis etiam post baptismi aquas reposita: quae nos sancti Spiritus sanctificet adventu, quae judicii igni nos decoquat, quae per mortis injuriam a labe morticinae et societate purgabit, quae martyrii passione devota ac fideli sanguine abluet. Sanctus Hilarius Pictaviensis, Tractatus super Psalmos, Tractatus in Psalmum CXVIII Source: Migne PL 9.519a-b

And if perhaps someone judges himself to have a perfection of innocence and a purity worthy of the heavenly life by baptism, let him recall what John the Baptist said, 'I baptise you with water for repentance, but he who comes after me is greater than me, who will baptise you with the Holy Spirit and fire.' 1 And the Lord Himself, having been baptised by John, when yet He was in the body, recalled what was spoken, 'I yet have another baptism to baptise.' 2 It is therefore eminently possible to think that a cleansing for perfect purity awaits after the waters of baptism, when we are sanctified by the coming of the Holy Spirit, who with the fire of judgement refines us so that we are purged of the wound of death and association with the fatal fall, which the passion of the martyr washes clean with devout and faithful blood. Saint Hilary of Poitiers, Homilies on the Psalms, from Psalm 118 1 Mt 3.11 2 Lk 12.50
