As discussed, an ordained Catholic priest is able to literally reprogram our souls in the Sacrament of Confession.
In Baptism, the same priest is able to wash away the Original Sin that Adam and Eve programmed into our genetic code. That washing away of sin prepares the soul for salvation. Without his programming ability, in all but the most special cases it would be impossible for the soul to attain Heaven.
In the Sacrament of the Holy Eucharist, “an angel takes the offering to the altar in Heaven” and then returns it. This cannot happen without a priest in attendance.
The actual re-programming is done instantaneously at the Heavenly altar. It cannot take place without the priest authorizing the Transubstantiation with the “Holy Password” that allows him to access The Mainframe.
