Acts 10:47

Can any man forbid water? &c. Or doubt that these, on whom the Holy Ghost hath descended, may be made members of the Christian Church, by baptism, as Christ ordained? (Witham) — Such may be the grace of God occasionally towards men, and such their great charity and contrition, that they may have remission, justification, and sanctification, before the external sacraments of baptism, confirmation, and penance be received; as we see in this example: where, at Peter’s preaching, they all received the Holy Ghost before any sacrament. But here we also learn one necessary lesson, that such, notwithstanding, must needs receive the sacraments appointed by Christ, which whosoever contemneth, can never be justified. (St. Augustine, sup. Levit. q. 84. T. 4.)

III. Their owning both Peter's word and God's work in their desire for further advantage by Peter's ministry: They prayed him to tarry certain days. They could not press him to reside constantly among them—they knew that he had work to do in other places, and that for the present he was expected at Jerusalem; yet they were not willing he should go away immediately, but earnestly begged he would stay for some time among them, that they might be further instructed by him in the things pertaining to the kingdom of God. Note, 1. Those who have some acquaintance with Christ cannot but covet more. 2. Even those that have received the Holy Ghost must see their need of the ministry of the word.

Verses 44-48 The Holy Ghost fell upon others after they were baptized, to confirm them in the faith; but upon these Gentiles before they were baptized, to show that God does not confine himself to outward signs. The Holy Ghost fell upon those who were neither circumcised nor baptized; it is the Spirit that quickeneth, the flesh profiteth nothing. They magnified God, and spake of Christ and the benefits of redemption. Whatever gift we are endued with, we ought to honour God with it. The believing Jews who were present, were astonished that the gift of the Holy Ghost was poured out upon the Gentiles also. By mistaken notions of things, we make difficult for ourselves as to the methods of Divine providence and grace. As they were undeniably baptized with the Holy Ghost, Peter concluded they were not to be refused the baptism of water, and the ordinance was administered. The argument is conclusive; can we deny the sign to those who have received the things signified? Those who have some acquaintance with Christ, cannot but desire more. Even those who have received the Holy Ghost, must see their need of daily learning more of the truth.
