I have read the first 128pp. of Fr. Wirth's book on Divine Grace (1903), and his is a classic example of an author who promotes 3 baptisms, and then 40 pages later contradicts what he previously said. I give a few citations from his book:
Three Baptisms:
"Baptism, according to the words of our Lord, 'Unless a man is born again of water and the Holy Ghost, he cannot enter the kingdom of God.' Baptism is absolutely necessary for salvation, so that no one can be saved without it. Only in case that it is impossible to receive the Baptism of water, the intense desire of it, joined with perfect contrition — that is, sorrow for sin out of the love of God, can replace it ; this is called the Baptism of desire....These are extraordinary ways of receiving the grace of justification ; the ordinary manner is by the Baptism of water. The Baptism of desire and the Baptism of blood give sanctifying grace only when the Baptism of water is impossible." (91-92)
The Necessity of Faith:
"Faith is therefore so necessary that one cannot be saved, even if it is without any fault of his own that he has not faith. Such a one is not disposed for eternal life, and he cannot obtain it any more than a man can see without eyes. Grown persons, i.e. they who have attained the use of reason, must not only have the virtue of faith, but they must also exercise certain acts of faith, in order to obtain eternal salvation." (127)
ibid:
"We cannot seek God without knowing that He exists, and we shall not seek Him unless we expect a reward from Him for our fidelity. These two things must therefore be believed explicitly by every adult, so that if one is ignorant of them, he cannot be saved even if it be without his fault that he is ignorant of them." (128)
