Virginmartyr Christina with her sister, at Caesarea, in Cappadocia

Saints Christina and Callista were sisters who once were Christians, but fearing torture, they renounced Christ and began to lead impious lives. The governor ordered them to persuade St Dorothy to offer sacrifice to the pagan gods, but just the reverse happened. St Dorothy convinced them that the mercy of God is granted to all who repent, so they corrected themselves and returned to Christ. The tormentors tied them back to back and burned them in a vat of tar. Sts Christina and Callista atoned for their sin of apostasy through martyrdom, receiving not only forgiveness, but crowns of victory from God.
