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.   Theodosius was several times guilty of anger and bloodshed during his reign, but, when corrected, always expressed sincere repentance and submitted himself to the authority and discipline of the Church. He endured a long excommunication and penance from Ambrose, bishop of Milan (December 7), for a massacre perpetrated at his order. Once he was about to enact bloody punishment of the people of Antioch for a rebellion, but relented when St Placilla (September 14) and Patriarch Flavian enjoined him to be merciful. In this, he showed a humility and submission to the Church almost unknown in Christian rulers before or since.   Having reigned for sixteen years, the Emperor Theodosius reposed in peace in 395 at the age of sixty.
