“Note that when Jesus says in The Gospel of Mark we need to believe AND be baptized, baptism is not a consequence of our salvation (as an if…then statement), but is conjoined to our faith for our salvation.”
how do you match this with the notion of baptism by blood and desire? It doesn't seem that water baptism is neccesery for salvation in catholic doctrine (at least so far as I understand it) only the disposition to be baptized. Though a ‘baptism’ of some sort is necessary.
The catechism says “God has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments.”
