And reckon ye that it is for your sakes we have been saying these things; for it is in our power, when we are examined, to deny that we are Christians; but we would not live by telling a lie. For, impelled by the desire of the eternal and pure life, we seek the above that is with God, the Father and Creator of all, and hasten to confess our faith, persuaded and convinced as we are that they who have proved to God by their works that they followed Him, and loved to abide with Him where there is no sin to cause disturbance, can obtain these things. This, then, to speak shortly is what we expect and have learned from Christ and teach.
“And what follows of the Psalm [21/22],—‘But Thou, Lord, do not remove Thine assistance from me; give heed to help me. Deliver my soul from the sword, and my only-begotten from the hand of the dog; save me from the lion’s mouth, and my humility from the horns of the unicorns,’ is indicative of the suffering by which He should die, i.e., by crucifixion. For the ‘horns of the unicorns,’ I have already explained to you, are the figure of the Cross only. And the prayer that His soul should be saved from the sword, and lion’s mouth, and hand of the dog, was a prayer that no one should take possession of His soul: so that, when we arrive at the end of life, we may ask the same petition from God, who is able to turn away every shameless evil angel from taking our souls.”
— St. Justin Martyr, The Second Apology, Chapter CV
“Unless, therefore, a man by God’s great grace receives the power to understand what has been said and done by the prophets, the appearance of being able to repeat the words or the deeds will not profit him, if he cannot explain the argument of them. And will they not assuredly appear contemptible to many, since they are related by those who understood them not?”
