Except, Bowler, that I didn't do anything beside quote and underline. I've given up on trying to explain things to you. So your problem is with the quoted authorities, and not with me.
It is impossible for venial sin to be in anyone with original sin alone, and without mortal sin. The reason for this is because before a man comes to the age of discretion, the lack of years hinders the use of reason and excuses him from mortal sin, wherefore, much more does it excuse him from venial sin, if he does anything which is such generically. But when he begins to have the use of reason, he is not entirely excused from the guilt of venial or mortal sin. Now the first thing that occurs to a man to think about then, is to deliberate about himself. And if he then direct himself to the due end, he will, by means of grace, receive the remission of original sin: whereas if he does not then direct himself to the due end, and as far as he is capable of discretion at that particular age, he will sin mortally, for through not doing that which is in his power to do. Accordingly thenceforward there cannot be venial sin in him without mortal, until afterwards all sin shall have been remitted to him through grace.
Who can deny that the act of perfect love of God, which is sufficient for justification, includes an implicit desire of Baptism, of Penance, and of the Eucharist. He who wishes the whole wishes the every part of that whole and all the means necessary for its attainment. In order to be justified without baptism, an infidel must love God above all things, and must have an universal will to observe all the divine precepts, among which the first is to receive baptism: and therefore in order to be justified it is necessary for him to have at least an implicit desire of that sacrament."
I underline because you still dubiously claim these quotes are about catechumens, as I would expect just about everyone beside you can see that they are not. If you still can't see that however, then I suggest going back to your 8th grade English grammar.
Unlike you, the others who agree with you have at least frankly stated that they disagree with these Doctors on this point. Whenever you come around, you should do the same.
By the way, if theologians want to say justification happens only by explicit faith, as indeed it does after the Gospel has been promulgated in a particular place, they say love of Christ in particular, and not love of God in general.
Pope Leo XIII, St. Pius X and Pius XII teach the same as these Doctors above, that where baptism cannot be had, an act of perfect love of God can supply the baptismal effect.
