Abstract
The study describes some fundamental elements of Eucharistic doctrine of St Ambrose of Milan. It develops the idea of the Eucharist as the Bread of Life, as Nourishment on the Way and focuses especially on the Forgiveness of Sins and Spiritual Marriage.
Especially the concept of Eucharist as Forgiveness of Sins is very original and it represents an invitation for the Christians of Milan to live every day from Christ who gives himself for them daily. Ambrose uses the means of a very personal symbolic theology to bring to the assembly not only the understanding of the Church doctrine, but also the desire to accomplish the union of the soul and the Church with the Christ.
On top of that, he offers the Eucharist as a real answer to real needs of the Christians of his days and not only as an institution adapted from the Scriptures and the Tradition, but recognising it and celebrating is as something precious.
