[3][4][5][6] Baithéne is still venerated in Ireland, but is most heavily associated with County Donegal where his cult was most active in Taughboyne and Culdaff.
[12] Baithéne is recorded in the four major Irish martyrologies as sharing his feast day with Columba on 9 June.
[15] The list gives Baithéne an alternative name 'Conin' and it mentions that he had a brother called Cobthach.
[12] Adomnán recorded a story about a voyage he took to the island, when Columba first told a monk who was heading to Tiree that he should not sail directly from Iona to Tiree, because a great whale would frighten him, but his did not listen to his advice and took the direct route, and a huge whale came out of the water and almost destroyed the boat, which terrified those in the boat.
When Baithéne departed the following day to Tiree, Columba told him about the whale, and Baithéne responded that both he and the whale were in God's power, to which Columba responded 'Go in peace, your faith in Christ will shield you from danger'.
[12] Another story that Adomnán recorded held that Baithéne and Colmán Elo both approached Columba one time to ask him to pray for a favourable wind on their respective journeys to Tiree and Ireland.
But after they fled, they then went to Tiree and attacked the monks there, including the monastery at Mag Luinge headed by Baithéne.
[18][19] In one story, Adomnán claimed that Columba went to Hinba and relaxed the penitential rules on one occasion.
This monk eventually left the monastery and went back into the world, and one day found himself among thieves eating such meat.
