Official state religionEmperor Constantine sought to have a universal religion. He made Roman Catholicism the official state religion, setting Sylvester, a non-Desposyni (David and Christ bloodline), as the head Bishop of the universal church. In 318, a delegation of Desposyni bishops from Palestine met with Sylvester in Rome, to urge him to continue recognising the preeminance of Jerusalem, and the continued selection of bishops by the Desposyni. Sylvester, having the backing of the Roman Emperor as head bishop of the new state religion, refused their request.
EasterConstantine ordered the First Council of Nicaea, where he decreed that Easter must be celebrated on Sunday, and forbid anyone from observing the Passover. He then issued an edict to confiscate the property of all Christians that continued observing the Passover, giving it to the Roman Catholic Church:
We have directed, accordingly, that you be deprived of all houses in which you are accustomed to hold your assemblies: and our care in this respect extends so far as to forbid the holding of your superstitious and senseless meetings, not in public merely, but in any private house or place whatsoever. Let those of you, therefore, who are desirous of embracing the true and pure religion, take the far better course of entering the Catholic Church, and uniting with it in holy fellowship, whereby you will be enabled to arrive at the knowledge of the truth.
And in order that this remedy may be applied with effectual power, we have commanded, as before said, that you be positively deprived of every gathering point for your superstitious meetings, I mean all the houses of prayer, if such be worthy of the name, which belong to heretics, and that these be made over without delay to the Catholic Church; that any other places be confiscated to the public service, and no facility whatever be left for any future gathering; in order that from this day forward none of your unlawful assemblies may presume to appear in any public or private place. Let this edict be made public.

JewsConcerning the Jews, Constantine said:
"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... Let us then have nothing in common with the detestable Jewish crowd..." (Ibid, Chap XVIII)
HereticsHe excommunicated Arius and his followers as heretics.
Baptism of ConstantineReports that Sylvester I baptised Emperor Constantine are false, as evidence has shown this was done by Eusebius, Bishop of Nicomedia.
