Tómméne

Saint Tómméne (also called Thoman, Thomanus, Thomenus, Thomian, Thomianus, Thomienus, Toimen, Toimene, Tóiméne, Tomiano, Tómíne, Tomini, Tomméin, Tommene,Tommine, Tomyn, Comméne, Comyn, Terenannus) b. c.580 - d.10 January 661, was the Bishop of Armagh, Ireland from 623 to 10 January 661.

St. Tómméne was probably a member of a tribe from North-East Ulster as was usual for Bishops of Armagh at this time. His father was Ronan. His genealogy does not appear to have survived but John Colgan stated he was the son of a chief, so it is probable his father was the ‘Ronan, son of Tuathal, Lord of the Airtheara’, who died in 620 according to the Annals of the Four Masters (AU 625, CS 625, AI 626). The Airtheara were an Airgialla tribe who ruled the district of Armagh. In which case his genealogy would be “Tómméne m Ronain m Tuathail m Oilella m Conaill m Feig m Bresail m Felim m Fiachra casan m Colla fo crith” According to Colgan- Tómméne grew up in great virtue, and from early youth he was remarkable for attention to study. Afterwards he was ranked among the most erudite of his countrymen, during an age most fruitful in the production of learned men.

On the death of Saint Mac Laisre, the Bishop of Armagh, on 12 September 623, St. Tómméne was appointed as the 16th coarb in succession to Saint Patrick. Saint Tómméne reigned as Bishop for 38 years.

At this time the Irish Church was preoccupied with the Paschal Question, i.e. how to compute the date of Easter and Christ’s death. St. Tómméne was interested in this dispute even before he was made Bishop of Armagh. A letter, written c.610 by Archbishop Laurence of Canterbury and countersigned by Mellitus, the Bishop of London and Justus, Bishop of Rochester, was sent to the Irish bishops urging them to adopt the Roman method of calculating Easter. According to John of Tinmouth and Capgrave (who mistakenly refer to Tómméne as Terenannus rather than Thomianus), Tómméne heard St. Laurence speaking on the matter and- “He thus laid hold of the truth, and afterwards took a great deal of pains, referable to those matters, in reforming his own people”. The southern part of Ireland accepted the Vatican computation at the Synod of Magh Lene in 630 A.D. However the Northern clergy were followers of the method proposed by Iona and its affiliate churches, known as the Irish Computation. In order to settle the matter Tómméne, with some other Ulster bishops and clergy, sent a letter in the first half of 640 to Pope Severinus setting out both sides of the argument and requesting his advice. However Pope Severinus died on 2 August 640 without having opened the letter. The future Pope John IV and others in the Vatican hierarchy replied to the letter sometime between August and Christmas 640, beginning as follows- “"Our most beloved and most holy Thomian, Columbanus, Croman, Diman, and Baithan bishops—to Croman, Hernian, Laistran, Scellan, and Segenus, presbyters—to Saran, and the rest of the Irish doctors or abbots." The Vatican was worried that the doctrine of Pelagianism was taking root in Ireland and advised against it in this letter.
