In the Tripartite Life of St Patrick (ed. Whitley Stokes) we read:
Bishop St Assic was Patrick's coppersmith, and made altars and square bookcases. Besides, he made our saint's patens in honour of Bishop Patrick, and of them I have seen three square patens, that is, a paten in the Church of Patrick in Armagh, and another in the Church of Elphin, and a third in the great-church of Donough-patrick (at Carns near Tulsk).Asicus was a coppersmith and was married when he first met St. Patrick. In time he was made the first abbot-bishop of Elphim Monastery in Roscommon, Ireland. Humble and not believing he was worthy of the office, Asicus went to an island in Donegal Bay, where he resigned his rank and became a hermit. After seven years the monks of Elphin found him and persuaded him to return to the monastery. He died at Raith Cungilor on the return journey.
St. Assicus was a most expert metal worker, and was also renowned as a bellfounder. Some remarkable specimens of his handicraft are extant. There is confusion between this saint and Tassach (April 14), which suggests that they may be the same person. They were both skilled metal workers, their names are similar, and they died the same year.
Of his last days the following graphic description is given by Archbishop Healy:
Assicus himself in shame because of a lie told either by him, or, as others say, of him, fled into Donegal, and for seven years abode in the island of Rathlin O'Birne. Then his monks sought him out, and after much labour found him in the mountain glens, and tried to bring him home to his own monastery at Elphin. But he fell sick by the way and died with them in the wilderness. So they buried the venerable old man in the churchyard of Rath Cunga, now Racoon, in the Barony of Tirhugh, County Donegal. The old churchyard is there still, though now disused, on the summit of a round hillock close to the left of the road from Ballyshannon to Donegal, about a mile to the south of the village of Ballintra. We sought in vain for any trace of an inscribed stone in the old churchyard. He fled from men during life, and, like Moses, his grave is hidden from them in death.
Propers for Assic of Elphin - Abbot-Bishop
O GOD, by whose grace the blessed (abbot) Assic 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 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.
