Early Life and Apostasy
He was born in the Galatea district of Constantinople and given the name Diamantes. His parents were named Kyriakos and Kyriake. Orphaned at a young age, he grew up undisciplined in his conduct.
By tradition, he was caught committing an unlawful act and, to escape punishment, agreed to convert to Islam — an apostasy from Christ that he later came to regret deeply. This fall, and the repentance that followed it, became the defining turn of his life.
