A man of great wisdom, he is known to have taken part in the fourth Council of Paris in 573.
[3] Felix was originally buried in the church of Austregisilus de Castro, outside the city's walls.
Gregory of Tours relates that twelve years after Felix's death, the stone slab which covered his remains was replaced by a slab of more precious material.
Several miracles were reported as having occurred to those who drank water containing some of the stone dust from the original slab.
[3] Felix had a strong devotion to the Holy Eucharist, and many miracles are attributed to his intercession.
