The Church commemorates Saint Sylvester, Pope of Rome, who was born in Rome and became Pope in AD 314. Thanks to his Orthodox faith, he managed to fight against the Arianism and established the liturgical practices of Chrismation.
Before being ordained to Bishop, he had performed many miracles and, therefore, many people believed in the Savior Christ. For instance, one of those who were converted to Christianity was Constantine the Great. At the instigation of Saint Sylvester, Constantine the Great built seven churches in order to glorify the Savior Christ and the Holy Martyrs. Saint Sylvester fell asleep in the Lord in old age.
