6 Who gave himself a ransom for all, to be testified in due time.
[AD 108] Ignatius of Antioch on 1 Timothy 2:6
Now I write these things unto you, not that I know there are any such persons among you; nay, indeed I hope that God will never permit any such report to reach my ears, He "who spared not His Son for the sake of His holy Church." But foreseeing the snares of the wicked one, I arm you beforehand by my admonitions, as my beloved and faithful children in Christ, furnishing you with the means of protection against the deadly disease of unruly men, by which do ye flee from the disease [referred to] by the good-will of Christ our Lord. Do ye therefore, clothing yourselves with meekness, become the imitators of His sufferings, and of His love, wherewith He loved us when He gave Himself a ransom for us, that He might cleanse us by His blood from our old ungodliness, and bestow life on us when we were almost on the point of perishing through the depravity that was in us. Let no one of you, therefore, cherish any grudge against his neighbour. For says our Lord, "Forgive, and it shall be forgiven unto you." Give no occasion to the Gentiles, lest "by means of a few foolish men the word and doctrine [of Christ.] be blasphemed." For says the prophet, as in the person of God, "Woe to him by whom my name is blasphemed among the Gentiles."

[AD 386] Cyril of Jerusalem on 1 Timothy 2:6
Do not wonder that the whole world was redeemed, for it was no mere man but the Only-begotten Son of God who died for it. The sin of one man, Adam, availed to bring death to the world; if by one man’s offense death reigned for the world, why should not life reign all the more “from the justice of the one?” If Adam and Eve were cast out of paradise because of the tree from which they ate, should not believers more easily enter into paradise because of the Tree of Jesus? If the first man, fashioned out of the earth, brought universal death, shall not he who fashioned him, being the Life, bring everlasting life? If Phinees by his zeal in slaying the evildoer appeased the wrath of God, shall not Jesus, who slew no other, but “gave himself a ransom for all,” take away God’s wrath against man?

[AD 407] John Chrysostom on 1 Timothy 2:6
Ver. 6. "Who gave Himself a ransom for all to be testified in due time."

Was Christ then a ransom for the Heathen? Undoubtedly Christ died even for Heathen; and you cannot bear to pray for them. Why then, you ask, did they not believe? Because they would not: but His part was done. His suffering was a "Testimony," he says; for He came, it is meant, "to bear witness to the truth" of the Father, and was slain. Thus not only the Father bore witness to Him, but He to the Father. "For I came," He says, "in my Father's name." [John 5:43] And again, "No man has seen God at any time." [John 1:18] And again, "That they might know You, the only true God." [John 17:3] And, "God is a Spirit," [John 4:24] And He bore witness even to the death. But this, "in due time," means, In the fittest time.
