After this Fintán arrived at the school of Saint Colum Cille, which was in Cell Mór Díthrib, and there he read the Holy Scripture with Columba. One day Saint Columba, as was his custom, was filled by the grace of the Holy Spirit and sang for much of the day about all the things that the Holy Spirit dictated to him. And, when he was finished, Columba said:
‘Who was nearest to me when I sang the words of the Holy Spirit’?
Baíthéne replied to him:
‘That boy, the son of Tulchán, was nearest to you by your right-hand side’.
Then Columba said:
‘He will be a spiritual teacher and most learned, surpassing everyone from this school’.
