Pious Emperor Theodosius the Great (395)

He was born in Spain, became a general in the Imperial Army, and was crowned Emperor of the East in 379. He quickly made his Orthodoxy clear by decisively rejecting Arianism, which had divided Christians, troubled the Church, and confused previous emperors, for many years. He summoned the Second Ecumenical Council at Constantinople in 381, which reaffirmed the doctrine of Nicaea and proclaimed the divinity of the Holy Spirit. While Constantine had outlawed the persecution of Christians and made Christianity the religion of the state, Theodosius outlawed the worship of idols within the Empire.
