“You have, to be sure, intimated that a certain Jew, when at the point of death, since he lived only among Jews, immersed himself in water while saying: ‘I baptize myself in the name of the Father, and of the Son, and of the Holy Spirit, Amen.’
We respond that, since there should be a distinction between the one baptizing and the one baptized, as is clearly gathered from the words of the Lord, when he says to the Apostles: ‘Go baptize all nations in the name etc.’ (cf. Matt. 28:19), the Jew mentioned must be baptized again by another, that it may be shown that he who is baptized is one person, and he who baptizes another... If, however, such a one had died immediately, he would have rushed to his heavenly home without delay because of the faith of the sacrament, although not because of the sacrament of faith.” (Pope Innocent III, Debitum pastoralis officii, August 28, 1206, Denzinger 413)
