St. Cyprian the martyr bishop of Carthage who was born in the century after St. John's death (A. D. 200) made an agreement with his friend Cornelius that whichever of them died first should in the Unseen Land remember in prayer him who was left behind. "Let us mutually be mindful of each other.... On both sides let us always pray for each other, let us relieve our afflictions and distresses by a reciprocity of love and whichever of us goes hence before the other by the speed of the Divine favour, let our affection continue before the Lord, let not prayer for our brothers and sisters cease before the mercy of the Father" (Ep. lvii. ad Cornel.). And in the days of the plague at Carthage, A. D. 252, he comforts his fellow citizens reminding them of "the large number of dear ones, parents, brothers, children, a goodly and numerous crowd longing for us and while their own immortality is assured still longing for our salvation." Origen, who was a contemporary of Cyprian, says, "All the souls who have departed this life still retaining their love for those who are in the world concern themselves for their salvation and aid them by their prayers and mediation with God. For it is written in the Book of the Maccabees, 'This is Jeremiah the prophet who always prays for the people'" (in Cant. Hom. iii.). And in another work he says, "It is my opinion that all those fathers who have fallen asleep before us fight on our side and aid us by their prayers" (in Jesu Nave Hom. xvi. ch. 19). And again "They (in that unseen life) understand who are worthy of Divine approval and are not only well disposed to these themselves, but coöperate with them in their endeavours to please God, they seek His favour on their behalf and with their prayers and intercessions they join their own." And again, "These (in the Unseen Life) pray for us and bring help to our perishable race, and if I may so speak, take up arms alongside of it" (Contra Celsum viii. 64). St. Gregory Nazianzen is preaching the funeral sermon of St. Basil. "He still prays for the people," he says, "for he did not so leave us as to have left us altogether." And in his funeral sermon over his own father, "I am satisfied that he accomplishes there now by his prayers more than he ever did by his teaching just in proportion as he approaches nearer to God after having shaken off the fetters of his body." St. Cyril, Bishop of Jerusalem, in his Catechetical lectures, and St. Chrysostom in several of his homilies speak of the help we get through the prayers of departed holy men. St. Ambrose in his great grief at his brother's death, says: "What other consolation is left me but this that I hope to come to thee my brother speedily, that thy departure will not entail a long separation between us, and that power may be granted me by thy intercessions that thou mayest summon me who long to join thee more speedily."
