First of all, by giving state patronage to only one branch of Christianity, the Catholic-Orthodox Church, and implicitly ensuring that his Edict of Milan was not seen as applying to the Gnostic Churches, he helped ensure the dominance of a single source of Christian teaching. He called and chaired the Council of Nicaea in order to establish a consistent and universal set of Church practices and doctrines. Although he did not participate directly in the debates and decisions of the Council, his leadership did ensure that issues, such as the divinity of Jesus, were addressed and ultimately agreed.
A:Until the time of Emperor Constantine, the main Christian Church was led by its bishops. The most revolutionary change Constantine made was to make the Roman emperor the absolute head of the Church. In taking on the role of appointing bishops, he declared, "My will be done."
There is no historical proof that Constantine the Great ever joined the church. All we have it the assertion of his friend Eusebius who was bishop of the church and would do anything to promote Christianity. After Constantine was dead and could not refute him, Eusebius claimed that he converted on his deathbed. You can make up your own mind as to the "conversion" of a man who had lived as a pagan all his life.

You may read a full discussion of Constantine at the link below. To the best of my knowledge the Catholic Church, which is the Mystical Body of Christ made no concessions to Constantine, rather, Constantine's mother was a Catholic, and Constantine was a catechumen, converting on his deathbed. Constantine, also legalized Christianity, and stopped the persecution of the Christians.
Constantine is not recognized as a saint in the Catholic Church so has no feast day. He is recognized as a saint in the Orthodox Church, however.
Martin Luther rebelled regarding the indulgences and practices of the Church, not about the teaching of the church which were created by a Roman leader named Constantine in 325 CE in Nicea. Many of the teachings were anti Jesus, nut inclusive.
The Magesterium has the ultimate teaching authority in the Catholic Church.
