I don't understand what you are saying, relative to our times. From the time of Adam and Eve till the after Our Lords resurrection, everyone that was saved, including the Holy Innocents, and the Good Thief, were saved without baptism. From the time that of Christ's resurrection , the sacrament of baptism became mandatory for all who were to be saved.
St. Augustine, Church Father and Doctor of the Church, clearly states that the Good thief was saved through baptism of desire. You need to stop making up your own Catholicism, Bowler:
The Seven Books of Augustin, Bishop of Hippo, On Baptism, Against the Donatists, Book IV, Ch 22: "That the place of baptism is sometimes supplied by martyrdom is supported by an argument by no means trivial, which the blessed Cyprian adduces from the thief, to whom, though he was not baptized, it was yet said, "To-day shall thou be with me in Paradise." On considering which, again and again, I find that not only martyrdom for the sake of Christ may supply what was wanting of baptism, but also faith and conversion of heart, if recourse may not be had to the celebration of the mystery of baptism for want of time. For neither was that thief crucified for the name of Christ, but as the reward of his own deeds; nor did he suffer because he believed, but he believed while suffering. It was shown, therefore, in the case of that thief, how great is the power even without the visible sacrament of baptism, of what the apostle says, "With the heart man believeth unto righteousness, and with the mouth confession is made unto salvation." But the want is supplied invisibly only when the administration of baptism is prevented, not by contempt for religion, but by the necessity of the moment."
Ch23: "But as in the thief, to whom the material administration of the sacrament was necessarily wanting, the salvation was complete, because it was spiritually present through his piety, so, when the sacrament itself is present, salvation is complete, if what the thief possessed be unavoidably wanting."
Ch24: "And as in the thief the gracious goodness of the Almighty supplied what had been wanting in the sacrament of baptism, because it had been missing not from pride or contempt, but from want of opportunity..."
Ch25: "By all these considerations it is proved that the sacrament of baptism is one thing, the conversion of the heart another; but that man's salvation is made complete through the two together. Nor are we to suppose that, if one of these be wanting, it necessarily follows that the other is wanting also; because the sacrament may exist in the infant without the conversion of the heart; and this was found to be possible without the sacrament in the case of the thief, God in either case filling up what was involuntarily wanting. But when either of these requisites is wanting intentionally, then the man is responsible for the omission. And baptism may exist when the conversion of the heart is wanting; but, with respect to such conversion, it may indeed be found when baptism has not been received, but never when it has been despised."
Note that St. Thomas Aquinas uses the same argument, referencing the quote from Saint Augustine above:
Whether three kinds of Baptism are fittingly described--viz. Baptism of Water, of Blood, and of the Spirit?Consequently, a man may, without Baptism of Water, receive the sacramental effect from Christ's Passion, in so far as he is conformed to Christ by suffering for Him. Hence it is written (Apoc. 7:14): "These are they who are come out of great tribulation, and have washed their robes and have made them white in the blood of the Lamb." In like manner a man receives the effect of Baptism by the power of the Holy Ghost, not only without Baptism of Water, but also without Baptism of Blood: forasmuch as his heart is moved by the Holy Ghost to believe in and love God and to repent of his sins: wherefore this is also called Baptism of Repentance. Of this it is written (Is. 4:4): "If the Lord shall wash away the filth of the daughters of Zion, and shall wash away the blood of Jerusalem out of the midst thereof, by the spirit of judgment, and by the spirit of burning." Thus, therefore, each of these other Baptisms is called Baptism, forasmuch as it takes the place of Baptism.
Wherefore Augustine says (De Unico Baptismo Parvulorum iv): "The Blessed Cyprian argues with considerable reason from the thief to whom, though not baptized, it was said: 'Today shalt thou be with Me in Paradise' that suffering can take the place of Baptism. Having weighed this in my mind again and again, I perceive that not only can suffering for the name of Christ supply for what was lacking in Baptism, but even faith and conversion of heart, if perchance on account of the stress of the times the celebration of the mystery of Baptism is not practicable."
