Constantine favored Christianity as a party but was not a Christian until he was on his deathbed, and he favored Arianism, which was not the faith of the majority because it was closer to his own faith, which was the worship of Sol Invictus. He also considered Judaism, but it was so peculiar, so national that he decided he could not subscribe to it, even though is many respects it was more like the pagan faiths. We see how he and his mother decided to build Christian temples to replace the old temples. She went to Jerusalem and laid the groundwork that led to the construction of the Church of the Holy Sepulcher and a Church of our Lady. If Constantine had chosen Judaism, he would have reconstructed the Jewish Temple.
Correct! Those who use Constantine against the Catholic Church are historically inaccurate.
All one needs to do is listen to the words of Saint Hilary of Poiters- who was far more influential than Constantine.
From Saint Hilary of Poiters
‘But nowadays, we have to do with a disguised persecutor, a smooth-tongued enemy, a Constantius who has put on Antichrist; who scourges us, not with lashes, but with caresses who instead of robbing us, which would give us spiritual life, bribes us with riches, that he may lead us to eternal death; who thrusts us not into the liberty of a prison, but into the honours of his palace, that he may enslave us: who tears not our flesh, but our hearts; who beheads not with a sword, but kills the soul with his gold; who sentences not by a herald that we are to be burnt, but covertly enkindles the fire of hell against us. He does not dispute with us, that he may conquer; but he flatters us, that so he may lord it over our souls. He confesses Christ, the better to deny him; he tries to procure a unity which shall destroy peace; he puts down some few heretics, so that he may also crush the Christians....-Saint Hilary of Poiters
I thought that "the whole world groaned to find itself Arian" in those days.
