Life of Saint Fintán, alias Munnu, abbot of Tech Munnu (Taghmon, Co. Wexford) (Author: [unknown])

Section 23

A youth from among the monachi named Fintán mac Éogain asked Fintán to let him go to visit his country.
Fintán said to him:
‘Go and take care not to drink anything but water until we greet each other [again]’.
And he blessed young Fintán's cup. Afterwards, the youth set out on the way [and] Fintán having died went to heaven. The youth heard of Fintán's death and so returned to his familia and refused to drink anything but water, for Fintán told him that he should not drink anything but water until they would greet each other [again]. The youth was therefore content with water for thirty years. One day, the abbot of the community whose name was Mo Chóemóc inadvertently tasted the water that was in that youth's cup and saw that it was most excellent wine, and that liquor stirred him from head to toe. And the abbot declared this to the youth. On hearing this that youth was confused and said to the abbot:
‘Give me the sacrament for on the third day I shall go to heaven, since another man on earth has revealed this. For my water tasted like this for thirty years since the day in which Fintán departed to heaven’; because Fintán blessed his cup.
