Roger.... man, I love you, brother, but you are stretching credulity with your explanation of Matt 28.... If it was only about "teaching" the nations, and making disciples of them, why would Jesus specifically say "teach them, make disciples of them, and baptize them in the name of the Father, Son, and Spirit" ? You cannot just write that off as some kind of meaningless, spurious comment!
And, a second point... nobody that believes in water baptism is "putting their faith" in the person performing the baptism.... any more than a Jewish man was putting his faith in the rabbi that did the bris. WHO does the baptism is immaterial... what is important is the ceremony itself. The person performing it has NO role in salvation... they are simply a tool.
