The doctrine matters. So often, whatever the method, clergy claim to make it an 'initiation' rite, whereby virtue and spiritual life are supposedly dispensed. Utterly false and giving of false hopes to people.
In contrast, in Acts 2.41, 'they that gladly received his word were baptised'. The baptism was a symbol that was observed by choice, by those who actively and willingly had already received the preaching of the Gospel of the Lord Jesus Christ.
The Greek word means to dip. In Acts, where Philip baptized the Ethiopian eunuch, there 'was much water there' and they descended into the water. The symbol is of burial of the old life, and emergence to the new one, which spiritually has already happened at the new birth, and the symbol demonstrates it, after the fact. (Acts 8.26-40)
