Another great Father of the Church who lived at the same time, was Ambrose. He was the Governor of the Italian city of Milan; and though a devout believer, was still unbaptized, when the clergy and the people, as was then the custom, met to choose their Bishop. A little child in the crowd cried out, "Ambrose Bishop!" and everyone took up the cry with one voice, and thought that the choice was inspired by the Holy Spirit. Ambrose was very unwilling to accept the office, but at last he submitted; he was baptized, and a week after was first confirmed, and then ordained priest, and consecrated Bishop. He was one of the most kind and gentle of men, but he had a hard struggle to fight for the truth. The Emperor, Valens, died, and his widow, Justina, who ruled for her little son, was an Arian. She wanted a church for her friends, but Ambrose would allow none to be profaned by a service where the blessed Saviour would be robbed of His honour. He knew his duty as a subject too well to lift a hand against the empress, but he filled up the Church with his faithful flock, and there they prayed, and sang psalms and hymns without ceasing; and when Justina sent soldiers to turn them out, they were so firm, that only one woman ran away. Instead of offering violence, the soldiers joined and prayed with them, and thus Justina was obliged to give up her attempt in despair. A very good emperor named Theodosius had begun to reign in the east, and assisted Justina's young son to govern the west. He was a thorough Catholic, and loved the Church with all his heart. Some fresh heretics had risen up, who taught falsehoods respecting the Third Person of the most Holy Trinity; and to put them down, Theodosius called another General Council to meet at Constantinople, and there the following addition was made to the Nicene Creed: "I believe in the Holy Ghost, the Lord and Giver of Life, Who proceedeth from the Father, Who with the Father and the Son together is worshipped and glorified--" and so on to the end. Thus each heresy was made the occasion of giving the faithful a beautiful watchword.
