Baptism has two effects: 1) it washes away original sin (and infuses faith, hope and charity into the soul), and 2) it imprints upon the soul an indelible character. The character is necessary to receive the other sacraments - which means the character (not sanctifying grace) is "strictly necessary as the gateway to the other sacraments".Nothing in the citation you quote from Ott implicitly refutes the Church's doctrine concerning baptism of desire. Dr. Ott himself explicitly teaches this doctrine on pages 356-358 of the book you quoted. As you will see in the following quotation, Ott, like every other theologian prior to Vatican II, interprets the Council of Trent as teaching baptism of desire.Fundamentals of Catholic Dogma, Ludwig Van Ott, p-356-357: "2. Substitutes for Sacramental Baptism: In case of emergency Baptism by water can be replaced by Baptism of desire or Baptism by blood. (Sent. fidei prox.)
if desire were sufficient to gains the effects of this sacrament ... it [water baptism] would not even be strictly necessary as the gateway to the other sacraments!
"a) Baptism of desire (Baptismus flaminis sive Spiritus Sancti) Baptism of desire is the explicit or implicit desire for sacramental baptism (votum baptismi) associated with perfect contrition (contrition based on charity).
"The Council of Trent teaches that justification from original sin is not possible " without the washing unto regeneration or the desire for the same."
"According to the teaching of Holy Writ, perfect love possesses justifying power. Luke 7, 47: "Many sins are forgiven her because she hath loved much." John 14, 21: " He that loveth me shall be loved of my Father: l and I will love him and will manifest myself to him." Luke 23, 43 • " This, day thou shalt be with me in Paradise."
"The chief witnesses from Tradition are St. Ambrose and St. Augustine. In the funeral oration on the Emperor Valentine II, who died without Baptism, St. Ambrose says: " Should he not acquire the grace for which he longed? Certainly: As he desired it, he has attained it . . . His pious desire has absolved him " (De obitu Valent. 51, 53). St. Augustine declared: "I find that not only suffering for the sake of Christ can replace that which is lacking in Baptism, but also faith and conversion of the heart (fidem conversionemque cordis), if perhaps the shortness of the time does not permit the celebration of the mystery , of Baptism " (De bapt. IV 22, 29). In the period of early Scholasticism St. ! Bernard of Clairvaux (Ep. 77 c. 2 n. 6-9), Hugo of St. Victor (De sacr. 116, 7) and the Summa Sententiarum (V 5) defended the possibility of Baptism of desire against Peter Abelard. Cf. S. th. III 68, 2.
"Baptism of desire works ex opere operantis. It bestows Sanctifying Grace, which remits original sin, all actual sins, and the eternal punishments for sin. Venial sins and temporal punishments for sin are remitted according to the intensity of the subjective disposition. The baptismal character is not imprinted nor is it the gateway to the other sacraments."He continues by explaining the Church's teaching concerning the baptism of blood:
Fundamentals of Catholic Dogma, Ludwig Van Ott, p. 357: b) Baptism of blood (baptismus sanguinis) Baptism of blood signifies martyrdom of an unbaptised person, that is, the patient bearing of a violent death or of an assault which of its nature leads to death, by reason of one's confession of the Christian faith, or one's practice of Christian virtue.
"Jesus Himself attests the justifying power of martyrdom. Mt. to, 32: "Every one therefore that shall confess me before men, I will also confess him before my Father who is in Heaven." Mt. 10 39 (16, 25): " He that findeth his life shall lose it: and he that shall lose his life for me shall find it." John 11 12, 25: " He that hateth his life in this world keepeth it unto life eternal."
"From the beginning the Fathers regarded martyrdom as a substitute for Baptism. Tertullian calls it "blood Baptism" (lavacrum sanguinis) and ascribes to it the effect of "taking the place of the baptismal bath if it was not received, and restoring that which was lost" (De bapt. I6). According to St. Cyprian, the catechumens who suffer martyrdom receive "
the glorious and most sublime blood-Baptism" (Ep. 73, 22). Cf. Augustine, De civ. Dei XIII 7.
"As, according to the testimony of Tradition and of the Church Liturgy (cf. Feast of the Innocents), young children can also receive blood-Baptism, blood-Baptism operates not merely ex opere operantis as does Baptism of desire, but since it is an objective confession of Faith it operates also quasi ex opere operato. It confers the grace of justification, and when proper dispositions are present, also the remission of all venial sins and temporal punishments. St. Augustine says: " It is an affront to a martyr to pray for him; we should rather recommend ourselves to his prayers "(Sermo 159 I.) Baptism by blood does not confer the baptismal character. Cf. S. th. III 66, 11 and 12."
This is the Church's teaching concerning baptism of desire and blood. It can be found expressed in similar terms in any pre-Vatican II theological manual and in the old catechisms. Those who depart from Tradition by rejecting BOD are no better than Modernists.
