My family goes to a well... i guess baptist church(it's sort of a "hipster" protestant church where noone at all wears a suit, the worship leader is a guy in skinny jeans, a v-neck t-shirt, and vans skate shoes,with distorted electric guitars and a band, no creeds, and the theology is baptist; they have no denomination listed nor do they call themselves non-denominational
Anyway the baptisms are so that the Pastor asks them "who do you trust as your lord and savior" they say "jesus christ" and then he dunks them once.
They are absolutely trinitarians but don't use the "father/son/holy spirit" as Catholicism says to, being that they see it as symbolic.
Does "baptism of desire" apply here? Are they all "not Christian"?
Also, does baptism require the words to be said as the person is being immersed? Is it valid if a pastor says "i baptize you in the name of the father, son, holy ghost" then immerses the person once?
