On the following day, however, Fintán said to Laisrén in the presence of all the people:
‘It is now time for this council to come to an end and for all to return to their loca. Therefore, I briefly say three things to Laisrén, namely: let our two books be cast into the fire, the book of the old rite and of the new rite, that we may see which book will escape the flames. Or let two of our monks be shut in a single house, and let the house be set alight, that we may see which of the two will be saved from the flames. Or let us both together, I and Laisrén, go to the grave of a long-dead just monk, and revive him, that he may reveal to us what Easter is celebrated this year in heaven’.
Laisrén said to him:
‘I will not go to judgement against the strong man of God. For, on account of the magnitude of your [good] works, if you were to command that Slíab Mairge change places with Mag nAilbe and that Mag nAilbe change places with Slíab Mairge, God would do this for you’.
Then Fintán said:
‘Therefore, let each and every one do as he believes and what seems right to him’.
