Actually the earliest method of baptism was not immersion but most likely pouring. Standing up in the water and the water poured on the head so it flowed down. John is often depicted baptizing Christ with water poured from a scallop shell in early christian art.
A study of early Christian baptismal by Professor M.M. Ninan states, “In every case the baptismal fonts were shallow pools where only the candidates feet were immersed. These were certainly unsuitable for total immersion as is practiced today. Even in the squatting mode, immersion could not be accomplished. Water was certainly poured on people from an overhead stream or from a pitcher held by the person baptizing".
The words baptise are simply Greek translated into English. No literal meaning such as "immersion" can be attached to the word baptize, because the same word is used to refer to washing, for example. Baptise by full immersion proponents say it means to dip...well it can, but it can also mean to put a liquid on something. The word for baptism includes immersion, sprinkling and pouring.
In comparison to baptism in the Spirit, the believers were also neither immersed or plunged into the Spirit, rather, baptism in the Spirit involved the Spirit being
poured out upon the believers, at Pentecost.
But nice try buddy
