Part 2: (Continued) These things, through God's mercy which was upon me, I then listened to attentively, and treasured them up not on paper, but in my heart ; and I am continually, by God's grace, revolving these things accurately in my mind."

From (1) Eusebius [Hist. EccL / Church History] , Book 5, Chapter 20 (in this Eusebius copies from Irenaeus' works)
This fragment is quoted by Eusebius, Hist. EccL, v. 20. It occurred at the close of the lost treatise of Irenaeus entitled De Ogdonde.

(2) This interesting extract we also owe to Eusebius, who (ut sup (meaning ut supra in Latin: as [the] above [statement of 1)] ) took it from the work De Ogdoade, written after this former friend of Irenaeus had lapsed to Valentinianism. Florinus had previously held that God was the author of evil, which sentiment Irenaeus opposed in a treatise.

Note: Irenaeus' original name is Εἰρηναῖος , which is in Greek and is a Greek name. Irenaeus' Greek name of Εἰρηναῖος is transliterated into English as Eirēnaios .

Polycarp stated he saw the Apostles and that they preached to him and the Philippians in his Epistle to the church at Philippi:
"9. I exhort you all therefore to be obedient unto the word of righteousness and to practise all endurance, which also ye saw with your own eyes in the blessed Ignatius and Zosimus and Rufus, yea and in others also who came from among yourselves, as well as in Paul himself and the rest of the Apostles; (Polycarp 9:1 on Page 180) LINK If then we entreat the Lord that He would forgive us, we also ought to forgive: for we are before the eyes of our Lord and God, and we must all stand at the judgment-seat of Christ, and all man must give an account of himself. Let us therefore so serve Him with fear and all reverence, as He himself gave commandment and the Apostles who preached the Gospel to us and the prophets who proclaimed beforehand the coming of our Lord ; being zealous as touching that which is good, abstaining from offences and from the false brethren and from them that bear the name of the Lord in hypocrisy, who lead foolish men astray. (Polycarp 6 on Page 179 LINK).
