Theophilus means, “loving God,” or “being loved by God.” Whoever then loves God, or desires to be loved by Him, let him think this Gospel to have been written to him, and preserve it as a gift presented to him, a pledge entrusted to his care. The promise was not to explain the meaning of certain new and strange things to Theophilus, but to set forth the truth of those words in which he had been instructed; as it is added, That thou mightest know the truth of those words in which thou hast been instructed; that is, “that thou mightest be able to know in what order each thing was said or done by the Lord.”
