There are other issues regarding the ‘millenium’ that is often assumed by the Catholic church to either have arisen from Bishop Papias and the ‘stories’ that he heard from the disciples regarding this time, or from those of the early church who took Rev.20:4-5 literally. Justin Martyr, Irenaeus, Tertullian, and Lactantius all have a millenial understanding of the Messianic age when Jesus Christ returns, but each of them is somewhat different from the other.
The exception to these is the Jewish Christian, Barnabas (100 AD). In his epistle, he describles the ‘seventh day’ as a millenial rest. (Much like some eschatological views of early Judaism).
It is very possible that the book of Revelation was not known to Barnabas at the time of his writing of the epistle. What is also sigificant is his introduction of the ‘eighth day’ as the beginning of a ‘new world’. A promise that was revealed by the resurrection of our Lord Jesus Christ on the eighth day as the ‘firstfruits’ from the dead. In other words, the Sabbath rest of the seventh day is the millenial of one thousand years, followed by the eighth day of the new creation, with Jesus Christ being the beginning of this new creation.
The Sabbath is mentioned at the beginning of the creation [thus]: “And God made in six days the works of His hands, and made an end on the seventh day, and rested on it, and sanctified it.” Attend, my children, to the meaning of this expression, “He finished in six days.” This implies that the Lord will finish all things in six thousand years, for a day is with Him a thousand years. And He Himself testifies, saying, “Behold, today will be as a thousand years.” Therefore, my children, in six days, that is, in six thousand years, all things will be finished. “And He rested on the seventh day.” This means: when His Son, coming [again], shall destroy the time of the wicked man, and judge the ungodly, and change the-sun, and the moon, and the stars, then shall He truly rest on the seventh day…
You perceive how He speaks: Your present Sabbaths are not acceptable to Me, but that is which I have made, [namely this,] when, giving rest to all things, I shall make a beginning of the eighth day, that is, a beginning of another world. Wherefore, also, we keep the eighth day with joyfulness, the day also on which Jesus rose again from the dead.
God’s peace to you
