Debaptism refers to the process of formally renouncing one's baptismal vows or severing oneself from the religious institution that administered the baptism. Some synonyms for debaptism include apostasy, renunciation, repudiation, disillusionment, disavowal, and abandonment. Apostasy denotes a complete abandonment of one's religious or political beliefs, while renunciation refers to the act of formally giving up or rejecting a claim or right. Repudiation is often used to convey the sense of rejecting something that was previously accepted, whereas disillusionment implies a loss of faith or trust in something that was once considered true or valuable. Disavowal and abandonment both suggest a deliberate rejection or abandonment of one's religious beliefs or affiliations.
