On When the Name Changes

The conferral of a new name across religious traditions marks a profound ontological rupture, signaling a transition from one state of being to another. In the Hebrew Bible, this transformation is often a unilateral divine decree establishing a covenantal reality. As Genesis 17:5 declares, "Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made." Here, the name change is inextricably linked to physical lineage and historical destiny, redefining the patriarch's function within the unfolding narrative of Israel. Similarly, in Christian texts, the renaming of Simon to Peter in Matthew 16:18 serves as a foundational act for the ecclesial community, anchoring his identity to the rock upon which the church is built. Yet, a meaningful divergence emerges when examining Islamic theology. While the Abrahamic traditions often depict naming as a transformative event altering an existing identity, the Qur'an emphasizes divine sovereignty over identity from the outset. In Surah Maryam 19:7, the angel announces, "O Zakariya! Lo! We bring thee tidings of a son whose name is John; we have given the same name to none before (him)." This suggests that the name was preordained rather than bestowed as a later modification. Thus, while all three traditions view the new name as a marker of a definitive break from the past, Judaism and Christianity often frame it as a change in status or function, whereas Islam frequently presents it as the revelation of a pre-existing, divinely known essence.
