While some sources say it was a continuation of the Synod of Brefi to condemn the heresy of Pelagianism,"David, Welsh saint", Dictionary of Early Christian Biography, (Henry Wace ed.) John Murray, London, 1911 others, such as Baring-Gould, say it was in regards to penitential canons.Baring-Gould, Sabine. "S. David", C. J. Clark, 1908, p. 285

In 550, Saint David attended the Synod of Brefi and spoke against Pelagianism. His speech led his fellow monks to elect him primate of the region. As primate he presided over the synod at Caerleon around 569.Toke, Leslie. "St. David." The Catholic Encyclopedia Vol. 4.
