BTW, baptism by sprinkling or of babies is not Biblical. Thats an adaptation of pagan practice.

There may be other definitions from other sources/religions.
Yes and No, it solely depends on the denomination (or even religion). You seem to be speaking of baptism as an immersion [as baptist churches do]. I'm going to quote this because i'm too lazy to think for myself today, " person baptized by immersion is enclosed under the water and brought out, to signify cleansing through death and burial with Christ, and consequent raising again in newness of life by the Holy Spirit."

What is your denomination or is there one you follow more than another? It sounds like you're antipaedobaptist, against aspersion and other forms of baptism outside of immersion...
