Hunyadi Demetrius, (sometimes written Huniades, and Hunjadinus,) was the second Superintendent of the Unitarian Church of Transylvania, in which office he succeeded the unfortunate Francis David, in 1579. It was not without opposition, that he was appointed to this situation ; but under his Superintendence, a union was effected among the Antitrinitarians of Transylvania, to which they probably owe their continued existence, as a religious body, to this day. He retained the office of Superintendent till his death, which took place in 1592, when he was succeeded by George Enyedi. His first object, after his appointment, was to compose a Confession of Faith, and to re-establish the Baptism of Infants in the name of the Father, Son and Holy Ghost, (and, as some say, the observance of the Lord's Supper,) which had fallen into disuse, during the Superintendence of F. David. Only about eighteen out of two hundred and seventy Ministers refused their assent to this Confession. The rest were gained over by the persuasion, or threats of Blandrata, at whose suggestion it was drawn up, and to whose revision it was submitted. It obtained the approbation of the general Synod, convened by Blandrata at Clausenburg, on the first of July, 1579. Hunyadi also composed, by the advice of Blandrata, a small tract, in which he exhorted the Church to resume the practice of Infant Baptism, &c. This was read in the Consistory of Clausenburg, Sept. 14th, 1579, before the Senate ; but appears not to have been printed.
