Well, Griff, allow me the opportunity to answer that question for you. Those Popes, Saints, Doctors, Fathers, and other formal doctrinal sources just didn't get it. Common man, get with the program. Obviously (hopefully) I'm being facetious. But it is interesting how far those go who insist on water Baptism/formal membership in the Church for salvation to be possible, without any exception, to try to make their position appear tenable. In order to appear to gain plausibility they have to deny, twist, and misquote an onslaught of authoritative docuмentation and hope we are stupid enough to fall for it.
There is one Baptism of God into Eternal Life which can be applied in three ways. The first is the ordinary means of being cleansed of Original Sin and is a Sacrament which is done with water. If one knows this must be done to obtain Eternal Life and refuses to do so he cannot be saved. The extraordinary forms of Baptism (or cleansing of Original Sin) are baptism of blood, when one, before he has the chance to be baptized, or due to inculpable ignorance of the need for Baptism, dies for Christ, and the third form of Baptism is baptism of the Holy Ghost and of repentance, generally phrased in English as, "baptism of 'desire'". Baptism of blood and baptism of desire will be referred to as [BOB/D] later in this docuмent. In Latin this third application of the one Baptism is called baptismus flaminis. While alive on earth, the only way to become of member of the Catholic Church is to be baptized sacramentally with water, profess the Faith, and submit to the Church's legitimate authority. Sacramental water Baptism is the only Baptism that gives the soul an indelible mark, and is what is required before one can receive any of the other sacraments. But the other two forms of Baptism cleanse the soul of Original Sin. Baptism of blood wipes away any penalty for past sins as does sacramental Baptism.
