Patriarch Photios I of
Constantinoplewas deposed as an usurper and his predecessor Saint Ignatius was reinstated. For his machinations which in the East were seen as heretical and divisive at that time, Photius had been declared deposed by the Pope earlier. The Churchof Constantinopleaccepted this at this, the The Fourth General Council of Constantinople. In the following centuries the East divided from West increasingly by political considerations of the East and the West insisting on its own interpretation of everything, in a snub thrown at the West, Photios was declared a saint by some – his life is anything but that.
After the Great Schism of the 11th century A.D. the Vatican started calling councils in the West starting with Lateran I.
|St. Ambrose of Milan|
St. Ambrose is the Church Father whose preaching led to the conversion of St. Augustine of Hippo, with the aid of St. Augustine's mother St. Monica's prayers for 16 years for her son to save him from hell. St. Augustine recounts his own conversion as coming to the point of confession in the True God when repenting of his profligate ways (he had lived without benefit of marriage with his lady friend for some years):
Latin of St. Ambrose
Glory to God in the Highest. And on earth peace to men of good will. We praise You.
You who take away the sins of the world: have mercy on us.
You who take away the sins of the world, receive our prayer.
Thou that sittest at the right hand of the Father, have mercy on us.
For you alone are holy. The Only Lord. You alone. Jesus Christ.
With the Holy Spirit, in the glory of God the Father. Amen
