Paragraph 100:
Thereupon saint Peter ordained that on the following day (which corresponds to the Sunday of the most holy Trinity), Baptism should be given to those who had been converted that week; this arrangement of saint Peter was satisfactory to our Queen and to the other Apostles. Immediately there arose a doubt as to what Baptism was to be given to them: the baptism of St. John or the Baptism of Christ our Savior. To some it seemed that the baptism of saint John, which was that of penance, should be given to them and that through it they were to enter the faith and justification of their souls. Others, on the contrary, said that with the Baptism and Death of Christ the baptism of saint John had expired, since it had served merely to prepare the souls for the reception of Christ the Redeemer, and the Baptism of the Lord gives grace sufficient for justifying the souls and for washing off all the sins from those properly disposed; and that it was necessary to introduce it immediately into the Church.
Paragraph 101:
This opinion was approved by saint John and saint Peter, and was confirmed by the most holy Mary. Hence they determined to institute at once the Baptism of Christ our Lord and to confer it on the new converts and the rest who came into the Church. In regard to the material and form of that Baptism there was no doubt among the Apostles; for all of them agreed that the material should be natural and elementary water and the form should be: I baptize thee in the name of the Father and of the Son and of the Holy Ghost; because these were the matter and the form designated by the Lord and Savior and these words He had made use of in the Baptism He had Himself administered. This way of baptizing was observed always from that day on. Wherever in the Acts of the Apostles it is said that they baptized in the name of Jesus, this saying does not refer to the form, but to the Author of the Baptism, namely Jesus, in contradistinction to the author of the other baptism, that of saint John. To baptize in the name of Jesus was the same as to baptize with with the Baptism of Jesus; but its form was that the Lord Himself had given and contains express mention of the three Persons of the most holy Trinity (Math. 27,19) as the foundation and beginning of all the Catholic truth and faith. The Apostles therefore ordained, that all the catechumens should gather in the house of the Cenacle in order to be baptized; and that the seventy two disciples should have charge of preparing them for that occasion.
