After the complete victory over the Arians Saint Ambrose created the solemn praise:
'We praise you, Lord.'
This hymn is being performed until today on every festive Thanksgiving and Praising of the Lord.
It was two years later, when all faithful were assembled in Milano to witness the baptism of Saint Augustine, that this hymn of Praise was sung to the Baptised and Baptising and from this time on formed part of the great body of church chants.
An unknown early biograph of Augustine writes:
'On the occasion of Augustine's conversion the blessed Ambrose praised the Holy Trinity with joyful singing and encouraged Augustine to confess his faith in honour of God.
'Ambrose blessed and praised the Lord and said:
'We praise you, my Lord, we confess in you, oh Lord.'
Augustine added: 'You, Eternal Father, the whole world praises.'
'All the angels and powers in Heaven praise you forever.'
Thus, in constant interplay, they sang the Hymn in honour of the Holy Trinity. Ambrose sang the first verse, Augustine the next. And Ambrose concluded the last verse thus: 'In you, my Lord, I set my hope, so that I will be eternally saved. Amen.'
... This hymn is being performed until today on every festive Thanksgiving and Praising of the Lord.
