12 Again I will remind you, my beloved, also of that which is written. For thus it is written, that when it was a grievous burden to Moses to lead the camp alone, the Lord said to him:— Lo! will take away of the Spirit that is upon you, and will put it upon seventy men, elders of Israel. But when He took away some of the Spirit of Moses, and the seventy men were filled with it, Moses nothing lacked, nor could it be known that anything was taken away from his Spirit.
Moreover the blessed apostle also said:— God divided of the Spirit of Christ and sent it into the Prophets. And Christ was in nothing injured, for it was not by measure that His Father gave unto Him the Spirit. By this reflection you can comprehend that Christ dwells in faithful men; yet Christ suffers no loss though He is divided among many. For the Prophets received of the Spirit of Christ, each one of them as he was able to bear. And of the Spirit of Christ again there is poured forth today upon all flesh, and the sons and the daughters prophesy, the old men and the youths, the men-servants and the hand-maids.
Something of Christ is in us, yet Christ is in heaven at the right hand of His Father. And Christ received the Spirit not by measure, but His Father loved Him and delivered all into His hands, and gave Him authority over all His treasure. For John said:— Not by measure did the Father give the Spirit to His Son, but loved Him and gave all into His hands. And also our Lord said:— All things have been delivered unto Me by My Father. Again he said:— The Father will not judge any man, but all judgment will He give unto His Son. Again also the Apostle said:— Everything shall be made subject unto Christ except His Father Who has subjected all unto Him.
And when everything is made subject unto Him by the Father, then He also shall be made subject to God His Father Who subjected all to Him, and God shall be all in all, and in every man.</em>
