The Baptism of Desire
Baptism by water opens the door of salvation, and the Church holds it to be necessary. Yet some die before receiving it: a catechumen taken the eve of his baptism, a martyr killed for Christ, a man who sought God without ever knowing the Gospel. God saves them by desire or by blood, where water was wanting.
The necessity of baptism
The Lord binds salvation to baptism: “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.” John 3:5 Baptism by water is the way Christ gave for receiving the grace that saves, and the Church knows no other assured means.
The baptism of desire
Whoever desires baptism and dies before receiving it obtains the grace by that very desire. The desire is explicit in the catechumen, who asks for baptism and prepares to receive it. It is implicit in the one who seeks God with a sincere heart and does his will according to what he knows of it: without naming Christ, he already desires him in desiring the good and the true. In both cases it is charity that gives the desire its worth, for the love of God contains in seed all that baptism confers.
The baptism of blood
Martyrdom likewise supplies for water. Whoever dies for Christ, or for a virtue that bears on him, is baptized in his own blood. He receives the grace by union with the Passion of Christ, which he reproduces in giving his life. The Church has always venerated as saints the martyrs who died before being baptized.
The thief on the cross
Scripture shows an example of this at Calvary. The thief crucified beside Jesus acknowledges his fault, confesses the innocence of Christ, and turns to him. Jesus answers him at once: “Today you will be with me in paradise.” Luke 23:43 This man did not receive baptism by water; his faith and his desire, at the threshold of death, opened paradise to him.
God is not bound by his sacraments
Baptism remains necessary, and no one may neglect it while holding back to desire or blood. But God, who attached salvation to the sacrament, is not himself chained to his signs: he can give when he wills the grace they contain. This is why the Apostle can say that God “desires all men to be saved and to come to the knowledge of the truth.” 1 Timothy 2:4 The baptism of desire and the baptism of blood are the way this will reaches those whom water has not attained.
