And looking at the texts of early Christians we see that they didn't baptize only by immersion. The Didache writting about 70-100 CE says "Concerning baptism, baptize in this manner: Having said all these things beforehand, baptize in the name of the Father and of the Son and of the Holy Spirit in living water [that is, in running water, as in a river]. If there is no living water, baptize in other water; and, if you are not able to use cold water, use warm. If you have neither, pour water three times upon the head in the name of the Father, Son, and Holy Spirit." These instructions were composed either while some of the apostles and disciples were still alive or during the next generation of Christians, and they represent an already established custom. Another early Christian leader (Hippolytus) explains ""If water is scarce, whether as a constant condition or on occasion, then use whatever water is available"
