 8 And many of the Corinthians, hearing, believed and were baptized (Acts 18:8).

The Origins and Development of Baptist Thought and Practice

Of course, the leaders' hands had no magical or mystical qualities. They merely symbolized and formally emphasized that God, not man, gave them authority and set them apart for a particular job. God commissioned them and issued them authority and jurisdiction to do His work. This again demonstrates one of the great lessons of the laying on of hands--that God works through man -- even in ordaining His own servants. ... Along with the physical act of baptism is promised the Holy Spirit -- through the laying on of hands. Millions have supposedly been baptized, but very few have had hands laid on them for the receiving of the Holy Spirit after baptism. (Bradley A. Laying On of Hands. Good News, February 1974)

Baptism was mostly done out-of-doors, but sometimes inside, but always by immersion. And clothed.

The populace came in great crowds to see John — mostly out of curiosity. But John was speaking in particular to the unrepentant religionists, as well as those who did repent. Notice carefully that some of those to whom John spoke — the repentant — were to be baptized with the Holy Spirit later. But the others present — among them many hypocritical, unrepentant Pharisees and Sadducees — were going to be baptized with fire — immersed in the lake of fire — unless they repented. They would be burned up as chaff (Matthew 3:12) (Sedliacik R. MINISTUDY: The BAPTISMS of the Bible. Good News magazine, April 1979).

The old Worldwide Church of God told ministerial trainees the following about baptismal counseling:

3...Others, again, lead them to a place where water is, and baptize them, with the utterance of these words, "Into the name of the unknown Father of the universe -- into truth, the mother of all things -- into Him who descended on Jesus -- into union, and redemption, and communion with the powers." Others still repeat certain Hebrew words, in order the more thoroughly to bewilder those who are being initiated, as follows: "Basema, Chamosse, Baoenaora, Mistadia, Ruada, Kousta, Babaphor, Kalachthei." The interpretation of these terms runs thus: "I invoke that which is above every power of the Father, which is called light, and good Spirit, and life, because Thou hast reigned in the body." Others, again, set forth the redemption thus: The name which is hidden from every deity, and dominion, and truth which Jesus of Nazareth was clothed with in the lives of the light of Christ -- of Christ, who lives by the Holy Ghost, for the angelic redemption. The name of restitution stands thus: Messia, Uphareg, Namempsoeman, Chaldoeaur, Mosomedoea, Acphranoe, Psaua, Jesus Nazaria...

Baptism, the Early Church, and the Continuing Church

Gregory of Tours (De gloria confess., c. 82) tells of a recluse named Eusitius who lived in the sixth century and possessed the power of curing quartan fever by giving its victims to drink of water that he had blessed; we might mention many other instances treasured up by this same Gregory ("De Miraculis S. Martini", II, xxxix; "Mirac. S. Juliani", II, iii, xxv, xxvi; "Liber de Passione S. Juliani"; "Vitae Patrum", c. iv, n. 3). It is known that some of the faithful believed that holy water possessed curative properties for certain diseases, and that this was true in a special manner of baptismal water. In some places it was carefully preserved throughout the year and, by reason of its having been used in baptism, was considered free from all corruption. This belief spread from East to West; and scarcely had baptism been administered, when the people would crown around with all sorts of vessels and take away the water, some keeping it carefully in their homes whilst others watered their fields, vineyards, and gardens with it ("Ordo rom. I", 42, in "Mus. ital.", II, 26). ( In )

I should probably add that while I do not know if any oil is used with Roman Catholic baptisms, that oil is placed in the baptismal fonts when they are blessed (normally by a bishop or priest). The Bible mentions water and the laying on of hands only (Acts 8:36; 19:5-6; see also ).

Show them that this is a worldwide Work with the greatest commission ever given to a group of human beings. Teach them that God isn’t calling people now just to give them salvation. If they don’t see and understand their responsibility to support this great Work mentally, spiritually, physically and emotionally — if they want baptism j ust so they can have personal salvation — if they don’t want to be a part of what God is doing — they’re not ready for baptism.
