Well there is that "indelible spiritual mark," "the seal of the Lord," "the sacramental character," which "no sin can erase" (CCC 1272- 1274) the character of Christ imprinted on the soul via baptism ex opere operato [by the act itself] which nothing can remove. This is why Catholics overall are so Godly in character versus evangelicals
.
And the ritual of baptism is considered to be so powerful by Rome that in cases of necessity baptism can be administered lawfully and validly by any person whatsoever if they fulfill the essential conditions, which are that the baptizer "pours water upon the one to be baptized, at the same time pronouncing the words: "I baptize thee in the name of the Father and of the Son and of the Holy Ghost." Moreover, "he must thereby intend really to baptize the person, or technically, he must intend to perform what the Church performs when administering this sacrament." (https://www.newadvent.org/cathen/02258b.htm)
Of course, Scripturally it is not the act itself of baptism (which in Scripture was by immersion) that effects regeneration, but the heart-purifying faith behind such obedience, (Acts 10:43;15:7-10)though since those who obey are those who believe, this regeneration is promised to those who will believe/obey (Acts 2:38) like as "thy sins be forgiven thee" was synonymous with healing/walking in the case of the palsied man, and which meant Christ had power to forgive sins. (Mark 2:8-11)
Moreover, Cyprian writes that “they who are baptized in the Church are presented to the bishops of the Church, and by our prayer and imposition of hands, they receive the Holy Ghost and are perfected with the seal of the Lord.” And elsewhere told his catechumens, “the Holy Ghost is about to seal your souls: you are to be enrolled in the army of the Great King." The Orthodox thus believe in laying on of hands (chrismation/unction) at the time of baptism, while Rome normatively makes this a separate later event above the age of discretion (now generally about 7) and which normally only a bishop can perform.
However, spiritually dead bishops cannot confer any spiritual power, and the separation of bishops (episkopos) from the office of elders (presbuteros) is a later unscriptural division, while Scripturally this "receiving" of the Holy Spirit in power evidently occurred at conversion (Acts 2:38; 10:43-47) or at conversion thru the laying on of hands thru a devout disciple, not an elder, (Acts 9:10,17; cf. Acts 22:12) or thru the apostles so doing. (Acts 8:14-18)
I know I have been born of the Spirit with its profound basic changes in heart and life - which certainly did not happen when I was baptized as kid or confirmed asa RC - but i cannot say I have had this second profound experience yet, though I pray.
