Today in History:
Constantine the Great Is Baptized
5.22.337

Today in history, on May 22, 337, Roman Emperor Constantine the Great was baptized on his deathbed, becoming the first Roman emperor to officially enter the Christian Church. Although Constantine had long supported Christianity—legalizing it through the Edict of Milan in 313 and playing a crucial role in its spread—he waited until his final days to receive the sacrament of baptism.

Constantine’s embrace of Christianity transformed the Roman Empire and laid the groundwork for the faith to become a global religion. He convened the First Council of Nicaea in 325, unifying Christian doctrine and establishing key tenets of the Church that still stand today.

His baptism, performed by Eusebius of Nicomedia, was a powerful final act that symbolized the union of imperial authority and Christian faith. Though delayed, it confirmed Constantine’s personal commitment to the religion he had helped legitimize and promote.

As we remember this day, Constantine’s baptism marks not only a personal spiritual milestone but also a defining moment in the history of Christianity and the Roman world.
