I found the description of the sacrament of baptism below to be personally true within the soul. To be “born again” by the action of the Spirit in these modern times reveals, (among a great many things), the historical reality of the presence of God in the flesh (Jesus) on earth . One learns confirmation of that visitation to his people, his death, and resurrection over 2000 years ago in one way–through the very same heart that was pierced by the Roman soldiers following his death on the cross. They wanted at that time in history to insure, with their own eyes, the death of the guilty ones; Yet, today, it is the same innocent blood and water mercifully flowing forth from the side of the Savior of the world which washes clean our sinful fallen souls, and enlightens the eyes and ears of our hearts in his bringing our souls into union with the Father—face to face in beatific communion with the Trinity. And there is no power, seen or unseen, nor evil spirit, or sin which plagues us, greater than this love of the Trinity, which God in His fullness of Glory desires to share with all men in the sacrament of baptism–Baptism reveals the meaning of life and the search for truth: To come to know, love, and serve God in this life, and be with him joyful forever in the next.
The following is from ‘Jesus of Nazareth, by Joseph Ratzinger, Pope Benedict XVI, pg. 20:
“Jesus’ Baptism, […] is understood as a repetition of the whole history, which both recapitulates the past and anticipates the future. His entering into the sins of others is a descent into the “inferno.” But he does not descend merely in the role of a spectator, as in Dante’s Inferno. Rather, he goes down in the role of one whose suffering-with-others is a transforming suffering that turns the underworld around, knocking down and flinging open the gates of the abyss. His Baptism is a descent into the house of the evil one, combat with the “strong man” (cf. Lk 11:22) who holds men captive (and the truth is that we are all very much captive to powers that anonymously manipulate us!). Throughout all its history, the world is powerless to defeat the “strong man”; he is overcome and bound by one yet stronger, who, because of his equality with God, can take upon himself all the sin of the world and then suffers it through to the end—omitting nothing on the downward path into identity with the fallen. This struggle is the “conversion” of being that brings it into a new condition, that prepares a new heaven and a new earth. Looked at from this angle, the sacrament of Baptism appears as the gift of participation in Jesus’ world-transforming struggle in the conversion of life that took place in his descent and ascent.”
