"St. Francis Borgia had great doubts about the salvation of those that have not a special devotion to Mary; because, according to St. Antonine, he who expects graces from God without the intercession of Mary attempts to fly without wings. St. Anselm has gone so far as to say: 'It is impossible to be saved if we turn away from thee, O Mary.' St. Bonaventure has said the same: 'He that neglects her will die in his sins.' Blessed Albertus Magnus says: 'The people that do not serve thee will perish.' And speaking of Mary, Richard of St. Laurence says: 'All those whom this ship does not receive are lost in the sea of this world.' But, on the other hand, he who is faithful in the service of Mary will be certainly saved. 'Oh Mother of God,' says St. John Damascene, 'if I put my confidence in you I shall be saved. If I am under your protection I have nothing to fear; for to be devoted to you is to have certain arms of salvation which God gives only to those whose salvation he wills in a special manner.'" St. Alphonsus De Liguori, in Dignity and Duties of the Priest, p 413-414 (published by the Redemptorist Fathers, copyright Very Rev. James Barron, C.SS.R., 1927, bearing the Nihil Obstat and Imprimatur of the Catholic Church).
Wow...that's pretty blatant isn't it? Not all Catholics would be so bold as to say that, but there are many who would.
Any of those blokes actually reponsible for writing Catholic docrine?
