The Great Martyr Demetrios the Wonderworker and Myrrh-streamer

There are actually conflicting accounts in the sources, but the overwhelming view is that he was born and bred in Thessaloniki. As a young man, he rose through the ranks of the Roman army because he was a very talented soldier. How he came to be introduced into the Christian faith we do not know, though it was not as usual as one might think for a high official. There were Christians even in the Roman imperial family: Theodora, the wife of Galerius, for example, who was beheaded in Thessaloniki on the orders of Emperor Licinius (ca. 315).
