BOOK IV (4)
Chapter XVI (16) - Perfect Righteousness Was Conferred Neither by Circumcision Nor by Any Other Legal Ceremonies. The Decalogue, However, Was Not Cancelled by Christ, But is Always in Force: Men Were Never Released from Its Commandments.
2. And that man was not justified by these things, but that they were given as a sign to the people, this fact shows,-that Abraham himself, without circumcision and without observance of Sabbaths, "believed God, and it was imputed unto him for righteousness; and he was called the friend of God." Then, again, Lot, without circumcision, was brought out from Sodom, receiving salvation from God. So also did Noah, pleasing God, although he was uncircumcised, receive the dimensions [of the ark], of the world of the second race [of men]. Enoch, too, pleasing God, without circumcision, discharged the office of God's legate to the angels although he was a man, and was translated, and is preserved until now as a witness of the just judgement of God, because the angels when they had transgressed fell to the earth for judgment, but the man who pleased [God] was translated for salvation (see "The Shepherd of Hermas", vision 4, 2[23]:5). Moreover, all the rest of the multitude of those righteous men who lived before Abraham, and of those patriarchs who preceded Moses, were justified independently of the things above mentioned, and without the law of Moses. As also Moses himself says to the people in Deuteronomy: "The Lord thy God formed a covenant in Horeb. The Lord formed not this covenant with your fathers, but for you" (Deuteronomy 5:2).
Chapter XI (21) - Abraham's faith was identical with ours; this faith was prefigured by the words and actions of the old patriarchs.
3. For to this end was the Lord born, the type of whose birth he set forth beforehand, of whom also John says in the Apocalypse: He went forth conquering, that He should conquer, Revelation 6:2.
Chapter XX (22) - That One God Formed All Things in the World, by Means of the Word and the Holy Spirit: and that Although He is to Us in This Life Invisible and Incomprehensible, Nevertheless He is Not Unknown; Inasmuch as His Works Do Declare Him, and His Word Has Shown that in Many Modes He May Be Seen and Known.
6. Men therefore shall see God, that they may live, being made immortal by that sight, and attaining even unto God; which, as I have already said, was declared figuratively by the prophets, that God should be seen by men who bear His Spirit [in them], and do always wait patiently for His coming. As also Moses says in Deuteronomy, "We shall see in that day that God will talk to man, and he shall live." For certain of these men used to see the prophetic Spirit and His active influences poured forth for all kinds of gifts; others, again, [beheld] the advent of the Lord, and that dispensation which obtained from the beginning, by which He accomplished the will of the Father with regard to things both celestial and terrestrial; and others [beheld] paternal glories adapted to the times, and to those who saw and who heard them then, and to all who were subsequently to hear them.
Chapter XXII (22) - Christ Did Not Come for the Sake of the Men of One Age Only, But for All Who, Living Righteously and Piously, Had Believed Upon Him; And for Those, Too, Who Shall Believe.
2. For it was not merely for those who believed on Him in the time of Tiberius Caesar that Christ came, nor did the Father exercise His providence for the men only who are now alive, but for all men altogether, who from the beginning, according to their capacity, in their generation have both feared and loved God, and practised justice and piety towards their neighbours, and have earnestly desired to see Christ, and to hear His voice. Wherefore He shall, at His second coming, first rouse from their sleep all persons of this description, and shall raise them up, as well as the rest who shall be judged, and give them a place in His kingdom. For it is truly "one God who" directed the patriarchs towards His dispensations, and "has justified the circumcision by faith, and the uncircumcision through faith." For as in the first we were prefigured, so, on the other hand, are they represented in us, that is, in the Church, and receive the recompense for those things which they accomplished.
