Thomas the Apostle, also known as Didymus, is renowned for his initial skepticism about Jesus’ resurrection, famously declaring he would not believe until he could see and touch Jesus’ wounds himself, a moment that epitomizes his rational character; this skepticism was transformed into profound faith when Jesus appeared and invited him to verify His wounds, leading Thomas to exclaim, “My Lord and my God!”—one of the clearest proclamations of Christ’s divinity in the New Testament. Post-resurrection, Thomas is believed to have traveled to India, where he established one of the oldest Christian communities and was eventually martyred, his legacy enduring as a symbol of faith that develops from personal encounter and sacrifice, commemorated as the patron saint of architects and the blind, with his feast days celebrated in both the Western and Eastern Churches.
