If I'm not mistaken, Constantine leaned toward the Arians before calling the Council of Nicaea.

He may have. Here is an interesting account of Constantine’s relationship with Arius after the council.

“It should be remembered that he did eventually (years after the Council) support the Arian party. A few years after the Council of Nicea, Arius discovered a new way to interpret the word "homoousius" that agreed with his doctrines. He then asked to be readmitted to communion, but the Church refused. Arius then appealed to the Emperor. Emperor Constantine's favorite sister, Constantia, on her deathbed, implored Constantine to support Arius and he did so. A date was set for the forcing of the Church to readmit Arius, but while he was waiting for Constantine to arrive Arius stopped to relive himself and his bowels burst and he died." (See Arians of the 4th Century, Chapter III, Section II by John Henry Newman)

Divine intervention?

Divine intervention?

No. That would be a miracle without Mary. Imagine the odds. :-)

Have you ever tried to "relive" yourself? Your bowels might burst too.

Divine Intervention? Maybe, Maybe not. There are many times throughout history when "convenient" deaths occurred.
