I will present Barnabas to start with:
Barnabas
Alexandria, Egypt
(AD 70-120)
Chapter 6 – The sufferings of Christ, and the new covenant, were announced by the prophets
[T]he prophet proclaimed, “Enter ye into the land flowing with milk and honey, and have dominion over it.” Behold, therefore, we have been refashioned, as again He says in another prophet, “Behold, saith the Lord, I will take away from these, that is, from those whom the Spirit of the Lord foresaw, their stony hearts, and I will put hearts of flesh within them,” because He was to be manifested in flesh, and to sojourn among us. For, my brethren, the habitation of our heart is a holy temple to the Lord. For again saith the Lord, “And wherewith shall I appear before the Lord my God, and be glorified?” He says, “I will confess to thee in the Church in the midst of my brethren; and I will praise thee in the midst of the assembly of the saints.” We, then, are they whom He has led into the good land. What, then, mean milk and honey? This, that as the infant is kept alive first by honey, and then by milk, so also we, being quickened and kept alive by the faith of the promise and by the word, shall live ruling over the earth. But He said above, “Let them increase, and rule over the fishes.” Who then is able to govern the beasts, or the fishes, or the fowls of heaven? For we ought to perceive that to govern implies authority, so that one should command and rule. If, therefore, this does not exist at present, yet still He has promised it to us. When? When we ourselves also have been made perfect [so as] to become heirs of the covenant of the Lord.
Barnabas spiritualises the Old Testament land promises in a manner that would cause modern premillennialists to go cross-eyed. This is a classic Amillennial approach to the fulfilment of Old Testament prophesies in a New Testament context. He also applies the promises made to natural Israel in the Old Testament to the New Testament church today.
Chapter 8. The red heifer a type of Christ
Now what do you suppose this to be a type of, that a command was given to Israel, that men of the greatest wickedness should offer a heifer, and slay and burn it, and, that then boys should take the ashes, and put these into vessels, and bind round a stick purple wool along with hyssop, and that thus the boys should sprinkle the people, one by one, in order that they might be purified from their sins? Consider how He speaks to you with simplicity.
The calf is Jesus: the sinful men offering it are those who led Him to the slaughter. But now the men are no longer guilty, are no longer regarded as sinners. And the boys that sprinkle are those that have proclaimed to us the remission of sins and purification of heart. To these He gave authority to preach the Gospel, being twelve in number, corresponding to the twelve tribes of Israel. But why are there three boys that sprinkle? To correspond to Abraham, and Isaac, and Jacob, because these were great with God. And why was the wool [placed] upon the wood? Because by wood Jesus holds His kingdom, so that [through the cross] those believing on Him shall live forever. But why was hyssop joined with the wool? Because in His kingdom the days will be evil and polluted in which we shall be saved, [and] because he who suffers in body is cured through the cleansing efficacy of hyssop. And on this account the things which stand thus are clear to us, but obscure to them because they did not hear the voice of the Lord.
Barnabas sees the kingdom as here now and also coming in the future. That fits in with the modern Amillennialist position which involves the “already/not yet” aspect to the kingdom of God. He acknowledges the current function of the Church now in this evil age, saying “in His kingdom the days will be evil and polluted in which we shall be saved.” This is an ongoing reality for this early Church writer. The kingdom to him involves an earthly experience before glorification.
Chapter XVI – The spiritual temple of God.
Moreover,
I will also tell you concerning the temple, how the wretched [Jews], wandering in error, trusted not in God Himself, but in the temple, as being the house of God. For almost after the manner of the Gentiles they worshipped Him in the temple. But learn how the Lord speaks, when abolishing it: “Who hath meted out heaven with a span, and the earth with his palm? Have not I?” “
Thus saith the Lord, Heaven is My throne, and the earth My footstool: what kind of house will ye build to Me, or what is the place of My rest?” Ye perceive that their hope is vain. Moreover, He again says,
“Behold, they who have cast down this temple, even they shall build it up again.” It has so happened. For through their going to war, it was destroyed by their enemies; and now: they, as the servants of their enemies, shall rebuild it. Again, it was revealed that the city and the temple and the people of Israel were to be given up. For the Scripture saith, “And it shall come to pass in the last days, that the Lord will deliver up the sheep of His pasture, and their sheep-fold and tower, to destruction.” And it so happened as the Lord had spoken.
Let us inquire, then, if there still is a temple of God. There is—where He himself declared He would make and finish it. For it is written, “And it shall come to pass, when the week is completed, the temple of God shall be built in glory in the name of the Lord.” I find, therefore, that a temple does exist. Learn, then, how it shall be built in the name of the Lord. Before we believed in God, the habitation of our heart was corrupt and weak, as being indeed like a temple made with hands. For it was full of idolatry, and was a habitation of demons, through our doing such things as were opposed to [the will of] God. But it shall be built, observe ye, in the name of the Lord, in order that the temple of the Lord may be built in glory. How? Learn [as follows]. Having received the forgiveness of sins, and placed our trust in the name of the Lord, we have become new creatures, formed again from the beginning. Wherefore in our habitation God truly dwells in us. How? His word of faith; His calling of promise; the wisdom of the statutes; the commands of the doctrine; He himself prophesying in us; He himself dwelling in us; opening to us who were enslaved by death the doors of the temple, that is, the mouth; and by giving us repentance introduced us into the incorruptible temple. He then, who wishes to be saved, looks not to man, but to Him who dwelleth in him, and speaketh in him, amazed at never having either heard him utter such words with his mouth, nor himself having ever desired to hear them. This is the spiritual temple built for the Lord.
For Barnabas, the temple of God is spiritual. It is revealed in the human heart. This temple is built up in place of the Jewish temple.
