ST MAC NESSI, ABBOT +c.590
The late eighth century “Martyrology of Tallaght”, Ireland’s most ancient book of saints, co-authored by Saint Oengus the Culdee and Saint Maelruain, provides early testimony to the veneration of the sixth-century abbot Saint Mac Nessi.
The latter governed the abbey of Clonmacnoise in County Offaly, Ireland, for sixteen years, from about 474 to about 590. He became abbot at a time when Clonmacnoise was at the height of its prosperity as a school of virtue.
No further details of Saint Mac Nessi’s life are known. In another hagiographic work of Saint Oengus, his famed poetic catalogue of Irish saints known as the Felire, Mac Nessi is referred to as “Mac Nessi the chaste”, indicating thereby that the saint was a man of exceptional purity of heart.
“Our soul is waiting for the Lord.
The Lord is our help and our shield.
May your love be upon us, O Lord,
as we place all our hope in you.”
