Brethren, we ought so to think of Jesus Christ, as of God, as of the Judge of the living and the dead.
Letter to Diognetus
…We might now be made deserving by the goodness of God, and having made clear our inability to enter into the kingdom of God of ourselves, might be enabled by the ability of God… Having then in the former time demonstrated the inability of our nature to obtain life, and having now revealed a Savior able to save even creatures which have no ability, He willed that for both reasons we should believe in His goodness and should regard Him as nurse, father, teacher, counselor, physician, mind, light, honor, glory, strength and life.
Grace; which confers understanding, which reveals mysteries, which announces seasons, which rejoices over the faithful, which is bestowed upon those who seek her, even those by whom the pledges of faith are not broken, nor the boundaries of the fathers overstepped. – ibid
Shepherd of Hermas
“I saw, Sir,” say I. “Thus,” said he, “no one shall enter into the kingdom of God, except he receive the name of His Son… Whosoever shall not receive His name, shall not enter into the kingdom of God.”
“They,” said he, “are holy spirits; and no man can otherwise be found in the kingdom of God, unless these shall clothe him with their garment; for if you receive only the name, but receive not the garment from them, you profit nothing… If [therefore] you bear the Name, and bear not His power, you shall bear His Name to none effect.” – ibid
Even those that bear His name with their whole heart. He Himself then is become their foundation, and He sustains them gladly, because they are not ashamed to bear His name.” – ibid
The first is Faith, and the second, Continence, and the third, Power, and the fourth, Long-suffering. But the others stationed between them have these names – Simplicity, Guilelessness, Purity, Cheerfulness, Truth, Understanding, Concord, Love. He that bears these names and the name of the Son of God shall be able to enter into the kingdom of God. – ibid
Clement of Rome
Let us look steadfastly to the blood of Christ, and see how precious that blood is to God, which, having been shed for our salvation, has set the grace of repentance before the whole world.
Let us therefore cleave unto those to whom grace is given from God … being justified by works and not by words. For He said; He that said much shall hear also again. Does the ready talker think to be righteous? – ibid
For He had mercy on us, and in His compassion saved us, having beheld in us much error and perdition, even when we had no hope of salvation, save that which came from Him. For He called us, when we were not, and from not being He willed us to be. – ibid
Though you saw Him not, you believe with joy unutterable and full of glory; unto which joy many desire to enter in; forasmuch as you know that it is by grace you are saved, not of works, but by the will of God through Jesus Christ. Wherefore gird up your loins and serve God in fear and truth, forsaking the vain and empty talking and the error of the many.
Clement of Alexandria
We must hear the savior speaking thus, “Come, follow Me.” For to the pure in heart He now becomes the way. But into the impure soul the grace of God finds no entrance.
For God conspires with willing souls. But if they abandon their eagerness, the spirit which is bestowed by God is also restrained. For to save the unwilling is the part of one exercising compulsion; but to save the willing, that of one showing grace. Nor does the kingdom of heaven belong to sleepers and sluggards…- ibid
