Rev. Father O'Brien had been for some years connected with the Redemptorists' Church of Our Lady of Perpetual Help, at Boston Highlands. He was in his thirty-sixth year at the time of his decease, which occurred suddenly on November 8th, from rheumatism of the heart, at Ilchester, Md., the parent house of the order. He had, only a few days previous to his death, closed a most arduous but successful mission in Philadelphia, where, but a short time previously, Rev. Father McGivern was taken with his fatal illness through overwork in his missionary labors. The remains of Father O'Brien were conveyed here by Mr. Cleary, one of our undertakers, and reposed in the main aisle fronting the altar of the Tremont Street basilica, during the evening and night of November 11, where many thousands visited them in tears, and rendered upward their silent and heartfelt prayers for the purposes which animated his sanctified soul. The emblems of mourning in the edifice, the varied and beautiful and artistic floral tributes, the grief depicted on the features of young and old of the people, and many other evidences, attested most unerringly the great bereavement which the Catholics of Boston sustain by his death.
The Late Rev. John O'Brien, C. S.S. R.
On the morning of the 12th, at 9 o'clock, the Redemptorist Fathers' Church was thronged with a great congregation, and hundreds were unable to get in when the office of the dead was recited. Over fifty priests participated in the sanctuary devotions. The clergymen offering up the Solemn High Mass of Requiem were as follows: Celebrant, Rev. Father Welsh, C. SS. R.; deacon, Rev. Father Wynn, C. SS. R.; sub-deacon, Rev. Father Lutz, C. SS. R.; master of ceremonies, Rev. Father Licking, C. SS. R.; Father Licking also preached the panegyric. The Reverend Father took for his text:
Ecclesiastes xii. 5 and 7. "Man shall enter into the house of his eternity, and the mourners shall go roundabout in the street.... And the dust shall return to the earth from whence it was, and the spirit shall return to God who gave it."
He began most impressively and substantially as follows: "What shall I say to you on this sad occasion? How shall I find words to express the sorrow and sadness, which I see depicted on your countenances? The zealous, the learned, the whole-souled Redemptorist, Rev. John O'Brien, is laid low on the bier of death. A young warrior has fallen on the battle-field of duty. A strong worker has sunk beside the vines he was preparing for the heavenly kingdom.
"Oh, brother, if thou hadst not died in the prime of youth! If thou hadst not within thee the strength and energy to labor long and successfully in thy sublime vocation! If thou hadst grown gray in the service of God, I should congratulate you on this day, the day of thy espousals to Jesus Christ. I should say to thee: well done thou faithful servant, thou hast labored long and well in the service of thy maker. Thou hast gone to thy well-merited reward." Father Licking continued at some length in this strong strain of apostrophe to the name and memory of his beloved brother, and then entered into reminiscences, in which he said, "I remember well when first I met the departed. It was in the year 1870. We were then students at the preparatory college of the Redemptorist order. He was even then the picture of health, and a model for every student. Never was he known to infringe upon the slightest rule of the institute; never (and this is saying a great thing), never did he lose a single moment of time. Always at his books by day and by night, even stealing from his well-merited rest some hours in order to acquire knowledge which he might employ in after years in the service of God and for the good of souls. So well pleased were his superiors with his conduct, that they appointed him, together with the late lamented Rev. Father McGivern, overseer of the college boys in the absence of their superiors."
He received the habit of the order in 1875, with Rev. Fathers Beal and Licking. The panegyrist made most feeling allusion to the occasion, when the lamented dead took "the profession of those holy vows, those tremendous vows, those eternal vows of poverty, chastity, and obedience.... Thank God, he kept those vows to the end."
Father O'Brien was next sent to the Redemptorist Theological Seminary of Ilchester, Md., to further pursue the great studies that fitted him for his calling.
