Acts 10, 45-49 Peter ordered them to be baptized

(Acts 10, 45-49) Peter ordered them to be baptized

[45] The circumcised believers who had accompanied Peter were astounded that the gift of the holy Spirit should have been poured out on the Gentiles also, [46] for they could hear them speaking in tongues and glorifying God. Then Peter responded, [47] "Can anyone withhold the water for baptizing these people, who have received the holy Spirit even as we have?" [48] He ordered them to be baptized in the name of Jesus Christ. [49] Then they invited him to stay for a few days.

(CCC 1226) From the very day of Pentecost the Church has celebrated and administered holy Baptism. Indeed St. Peter declares to the crowd astounded by his preaching: "Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit" (Acts 2:38). The apostles and their collaborators offer Baptism to anyone who believed in Jesus: Jews, the God-fearing, pagans (Cf. Acts 2:41; 8:12-13; 10:48; 16:15). Always, Baptism is seen as connected with faith: "Believe in the Lord Jesus, and you will be saved, you and your household," St. Paul declared to his jailer in Philippi. And the narrative continues, the jailer "was baptized at once, with all his family" (Acts 16:31-33). (CCC 683) "No one can say 'Jesus is Lord' except by the Holy Spirit" (1 Cor 12:3). "God has sent the Spirit of his Son into our hearts, crying, 'Abba! Father!"' (Gal 4:6). This knowledge of faith is possible only in the Holy Spirit: to be in touch with Christ, we must first have been touched by the Holy Spirit. He comes to meet us and kindles faith in us. By virtue of our Baptism, the first sacrament of the faith, the Holy Spirit in the Church communicates to us, intimately and personally, the life that originates in the Father and is offered to us in the Son. Baptism gives us the grace of new birth in God the Father, through his Son, in the Holy Spirit. For those who bear God's Spirit are led to the Word, that is, to the Son, and the Son presents them to the Father, and the Father confers incorruptibility on them. And it is impossible to see God's Son without the Spirit, and no one can approach the Father without the Son, for the knowledge of the Father is the Son, and the knowledge of God's Son is obtained through the Holy Spirit (St. Irenaeus, Dem. Ap. 7: SCh 62, 41-42).
