I do not doubt that all those who have received Baptism anywhere and from whomever do have Baptism, as long as it was consecrated with the words of the Gospel and they received it without pretence on their part and with some degree of faith. However, it would not avail them for their spiritual salvation if they were lacking in that charity by which they might be implanted in the Catholic Church.
Saint AugustineO eternal truth and true love and beloved eternity! You are my God; to you I sigh by day and by night. And when I first knew you, you raised me up so that I could see that there was something to see and that I still lacked the ability to see it. And you beat back the weakness of my sight, blazing upon me with your rays, and I trembled in love and in dread.
Saint AugustineFor whenever unbaptized persons die confessing Christ, this confession is of the same efficacy for the remission of sins as if they were washed in the sacred font of baptism.
Saint AugustineDo not follow any road, but that which Christ trod. This road seems hard, but it is safe.
Saint AugustineBy means of corporal and temporal things we may comprehend the eternal and the spiritual.
Saint AugustineTherefore once for all this short command is given to you. 'Love and do what you will.' If you keep silent, keep silent by love; if you speak, speak by love; if you correct, correct by love; if you pardon, pardon by love: let love be rooted in you, and from the root nothing but good can grow.
Saint Augustine
