Deiniol of Bangor

According to a Latin Life of Deiniol, preserved in Peniarth MS226 and transcribed in 1602 by Sir Thomas Williams of Trefriw, he was the son of Abbot Dunod Fawr, son of Pabo Post Prydain. The family, having lost their land in the North of England, were given land by the king of Powys, Cyngen ap Cadell. Dunod, embraced the religious life and founded the monastery at Bangor-is-y-coed on the Dee.

Deiniol is said to have studied under Cadoc of Llancarfan. Sir David Trevor describes Deiniol as one of the seven blessed cousins who had spent part of his early life as a hermit "on the arm of Pembrokeshire" but was called to be a bishop despite deficiencies in his formal education. Deiniol soon left Powys for Gwynedd where he founded the monastery of Bangor under the patronage of Maelgwn Gwynedd who endowed it with lands and privileges, later raising it to the rank of the official seat of a bishop, sharing a common boundary with the principality of Gwynedd. Deiniol spent the remainder of his days here as Abbot and Bishop.

He attended the Synod of Llanddewi Brefi in c. 545 with Saint David when the subject of rules for penance was being discussed. He was apparently consecrated in 545 by David. According to the Annales Cambriae Deiniol died in 584 and was buried on Bardsey Island.

His cult in North Wales was quite extensive although there are not many churches dedicated to him. 

Propers for Deiniol of Bangor - 11 September - Monastic and Bishop

The Collect

O GOD, by whose grace the blessed Deiniol of Bangor enkindled with the fire of thy love, became a burning and a shining light in thy Church: Grant that we may be inflamed with the same spirit of discipline and love, and ever walk before thee as children of light; through Jesus Christ our Lord. Amen.

The Epistle - Philippians 3:7-15.

HOWBEIT what things were gain to me, these have I counted loss for Christ. Yea verily, and I count all things to be loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I suffer the loss of all things, and do count them but dung, that I may gain Christ, and be found in him, not having a righteousness of mine own, even that which is of the law, but that which is through faith in Christ, the righteousness which is of God by faith: that I may know him, and the power of his resurrection, and the fellowship of his sufferings, becoming conformed unto his death; if by any means I may attain unto the resurrection of the dead. Not that I have already obtained, or am already made perfect: but I press on, if so be that I may apprehend that for which also I was apprehended by Christ Jesus. Brethren, I count not myself yet to have apprehended: but one thing I do, forgetting the things which are behind, and stretching forward to the things which are before, I press on toward the goal unto the prize of the high calling of God in Christ Jesus. Let us therefore, as many as be perfect, be thus minded: and if in anything ye are otherwise minded, even this shall God reveal unto you. 

The Holy The Gospel - St. Luke 12:22-37.

JESUS said unto his disciples, Therefore I say unto you. Be not anxious for your life, what ye shall eat; neither for the body, what ye shall put on. The life is more than meat, and the body is more than raiment. Consider the ravens: for they neither sow nor reap; which neither have storehouse nor barn; and God feedeth them: how much more are ye better than the fowls? And which of you by being anxious can add a cubit to his span of life? If ye then be not able to do that which is least, why are ye anxious for the rest? Consider the lilies how they grow: they toil not, they spin not; and yet I say unto you, that Solomon in all his glory was not arrayed like one of these. If then God so clothe the grass, which is to day in the field, and to morrow is cast into the oven; how much more will he clothe you, O ye of little faith? And seek not ye what ye shall eat, or what ye shall drink, neither be ye of anxious mind. For all these things do the nations of the world seek after: and your Father knoweth that ye have need of these things. But rather seek ye the kingdom of God; and all these things shall he added unto you. Fear not, little flock; for it is your Father's good pleasure to give you the kingdom. Sell that ye have, and give alms; provide yourselves bags which wax not old, a treasure in the heavens that faileth not, where no thief approacheth, neither moth corrupteth. For where your treasure is, there will your heart be also. Let your loins be girded about, and your lamps burning; and ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately. Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them.
