How may baptisms are there in the RCC.? According to acts19 there is water baptism and holy spirit baptism.
There is only one Baptism. The Church teaches that “Baptism is the first and chief sacrament of the forgiveness of sins: it unites us to Christ, who died and rose, and gives us the Holy Spirit (*Catechism of the Catholic Church * no. 985, 977). Baptism is birth into the new life in Christ. In accordance with the Lord’s will, it is necessary for salvation, as is the Church herself, which we enter by Baptism…Given once for all, Baptism cannot be repeated” (ibid. 1277, 1272).
Acts 19:6 is speaking of the reception of the sacrament of baptism and confirmation.
“From that time on the apostles, in fulfillment of Christ’s will, imparted to the newly baptized by the laying on of hands the gift of the Spirit that completes the grace of Baptism. For this reason in the Letter to the Hebrews the doctrine concerning Baptism and the laying on of hands is listed among the first elements of Christian instruction. The imposition of hands is rightly recognized by the Catholic tradition as the origin of the sacrament of Confirmation, which in a certain way perpetuates the grace of Pentecost in the Church.” (CCC 1288)
“The bishop, imposing his hand on them, shall make an invocation, saying, ‘O Lord God, who made them worthy of the remission of sins through the Holy Spirit’s washing unto rebirth, send into them your grace so that they may serve you according to your will, for there is glory to you, to the Father and the Son with the Holy Spirit, in the holy Church, both now and through the ages of ages. Amen.’ Then, pouring the consecrated oil into his hand and imposing it on the head of the baptized, he shall say, ‘I anoint you with holy oil in the Lord, the Father Almighty, and Christ Jesus and the Holy Spirit.’ Signing them on the forehead, he shall kiss them and say, ‘The Lord be with you.’ He that has been signed shall say, ‘And with your spirit.’ Thus shall he do to each” (The Apostolic Tradition 21–22 [A.D. 215]).
