Every single baptism I've ever witnessed over the course of 37 years of being a Christian.
Hardly ever! They stick their head under water and holler “I baptise you in the name of JESUS”!!
And you know this how? You witnessed it yourself? Repeatedly? Every single time?
Who did this and when?
How many are you eyewitness accounts to? When the Catholic church accepts as valid a Protestant baptism, it by default acknowledges that it was done according to the Trinitarian formula.
So since the Catholic church accepts as valid the baptism of Protestant denominations, then why are you disagreeing with the Catholic church?
Isn't that a sin of some sort or another?
