The Fathers Speak: The Church Keeps Laughing
“Isaac also, delivered from death, laughed, sporting and rejoicing with his spouse, who was the type of the helper of our salvation, the church, to whom the stable name of endurance is given for this reason: because she alone remains to all generations, rejoicing ever, subsisting as she does by the endurance of believers, who are the members of Christ. . . . The King, then, who is Christ, beholds from above our laughter, and looking through the window, as the Scripture says, views the thanksgiving and the blessing and the rejoicing and the gladness and furthermore the endurance that works together with them and their embrace. Thus he views his church, showing only his face, which before was hidden to the church, which is made perfect by her royal head.”
— Clement of Alexandria
Christ and Educator, 1.5.27.
