Constantine was the Roman Emperor from 306-337 AD. The thoughts concerning the Jews that Constantine held did not appear overnight. We can say with absolute certainty that the understanding of the gospel concerning Israel which Paul had written extensively in Romans was corrupted before 300AD. It was! It must be clearly understood in the grace of God that Constantine and his edicts are the purpose of God, not of the justification of the spirit, but of the condemnation of the letter. But the works of men according to the flesh do not hinder the purpose of God. No, it shall never be! For “all Israel shall be saved.”
The Gentiles who wrongly condemned the Jews for the crucifixion of the Christ, not understanding that it was God who purposed these things, have found the ministry of condemnation passed on to them. For both Jew and Gentile are partakers-the ministry of the letter of the Law. Both Jew and Gentiles have been entrusted with the oracles of God and the end shall be the same for both-the judgment of God! The Gentiles with the greater light of the gospel did not and do not understand to this day, that first and foremost, that Yeshua’s death for our sins, His burial and His resurrection the third day was ACCORDING TO ALL THE SCRIPTURES, PURPOSED BY GOD. This is the one true gospel. (Luke 24, 1Cor 15:1-6) They do not understand that Rome was God’s instrument of judgment upon His Son and upon Yerusalem in 70AD. But God has had a people in all generations chosen by Him who partake of the ministry of justification and love in Christ Yeshua, a remnant of grace. The gates of sheol has not and will not prevail against the assembly of the living God. Death and condemnation will not prevail against the saints of the most High God.
The following exert is taken from Wikepedia, the subject being Constantine. There is much witness to the words written, if there be any who would argue with this history. He fulfilled the purpose of God but not justification.
“Constantine instituted several legislative measures regarding the Jews: they were forbidden to own Christian slaves or to circumcise their slaves. Conversion of Christians to Judaism was outlawed. Congregations for religious services were restricted, but Jews were allowed to enter Jerusalem on Tisha B’Av, the anniversary of the destruction of the Temple. Constantine also supported the separation of the date of Easter from the Jewish Passover (see also Quartodecimanism), stating in his letter after the First Council of Nicaea: “… it appeared an unworthy thing that in the celebration of this most holy feast we should follow the practice of the Jews, who have impiously defiled their hands with enormous sin, and are, therefore, deservedly afflicted with blindness of soul. … Let us then have nothing in common with the detestable Jewish crowd; for we have received from our Saviour a different way.” . Theodoret‘s Ecclesiastical History 1.9 records the Epistle of the Emperor Constantine addressed to those Bishops who were not present at the Council: “It was, in the first place, declared improper to follow the custom of the Jews in the celebration of this holy festival, because, their hands having been stained with crime, the minds of these wretched men are necessarily blinded. … Let us, then, have nothing in common with the Jews, who are our adversaries. … avoiding all contact with that evil way. … who, after having compassed the death of the Lord, being out of their minds, are guided not by sound reason, but by an unrestrained passion, wherever their innate madness carries them. … a people so utterly depraved. … Therefore, this irregularity must be corrected, in order that we may no more have any thing in common with those parricides and the murderers of our Lord. … no single point in common with the perjury of the Jews.” ”
Beloved, children of grace, God loves all people of all nations without partiality, Of Yisrael and the nations (the Gentiles). This is the love of God in the Mashiach who died for all people, who tasted death for all people. This is the love of God shed abroad in our hearts by the Holy Spirit who was given to us. Constantine at the very best was a false prophet and all who follow after him and all he followed after concerning Yisrael, walk in great error.
