The Commemoration
The saint is listed under November 28 as "Martyr Hristo of Bulgaria," of Bulgarian origin and of an era the received record leaves unspecified. The entry survives as a name preserved in the calendar; the Orthodox Church in America's account offers no accompanying life, stating that no information is available.
The commemoration appears across multiple Orthodox calendars, including those associated with the Moscow Patriarchate, the Russian Orthodox Church Outside Russia, and the Orthodox Church in America.
