Cyril of Jerusalem was an illustrious theologian and bishop of Jerusalem. His care for the poor and his doctrine on the Eucharist were equally talked about! His most noteworthy work was his Catechetical Lectures, which contain invaluable instructions on several topics of the Christian faith. His pastoral care and warmth as well as his deep grasp of the Scriptures were undoubtedly evident. He also gave a thorough adhesion to the Nicene orthodoxy.
