Acts 2:38

Be baptized: believing and making profession to believe, and hope for salvation, by the merits of Jesus Christ. Thus you shall receive the gift of the Holy Ghost, the grace of God, and perhaps those other gifts of speaking with tongues, working miracles, &c. (Witham) --- The gift of the Holy Ghost. That is, justifying grace, which is infused in our hearts by the laver of regeneration. The exterior gifts of the Holy Ghost, the gifts of tongues, of miracles, prophecy, &c. were, in the beginning of the Church, more regularly the consequence of confirmation or imposition of hands. (Calmet)
