That they might receive the Holy Ghost. Why was it needful that two apostles should come down to Samaria and pray, with laying on of hands, for the newly baptized that they might receive the Holy Ghost?
There is no mention of such prayer or such imposition of hands in the case of the first three thousand who were baptized. They were told by St. Peter, "Be baptized every one of you, and ye shall receive the gift of the Holy Ghost" (Acts 2:38), and they were baptized, and doubtless did receive the Holy Ghost, Neither is there any mention of such things in the case of the subsequent thousands who were baptized at Jerusalem on the apostles' preaching.
Why, then, was it so in Samaria? To answer this question, we must observe the difference in the circumstances. The baptisms at Jerusalem were performed by the apostles themselves. The Holy Ghost was given upon their promise and assurance.
But in Samaria the preaching and the baptizing were done by the scattered disciples. There was a danger of many independent bodies springing up, owing no allegiance to the apostles, and cemented by no bonds to the mother Church.
But Christ's Church was to be one—many members, but one body. The apostolate was to be the governing power of the whole Church, by the will and ordinance of Christ. Hence there was a manifest reason why, when the gospel spread beyond Judaea, these visible spiritual gifts should be given only through the laying on of the apostles' hands, and by the intervention of their prayers.
This had a manifest and striking influence in marking and preserving the unity of the Church, and in marking and maintaining the sovereignty of the apostolic rule. For precisely the same reason has the Catholic and Apostolic Church in all ages (Acts 19:5, Acts 19:6; Hebrews 6:2) maintained the rite of confirmation, "after the example of the holy apostles."
Besides the other great benefits connected with it, its influence in binding up in the unity of the Church the numerous parishes of the diocese, instead of letting them become independent congregations, is very great.
Observe, too, how prayer and the laying on of hands are tied together. Neither is valid without the other. In this case, as at Pentecost, the extraordinary gift of the Holy Ghost was conferred. In confirmation, now that miracles have ceased, it is the ordinary and invisible grace of the Holy Spirit that is to be looked for.
