In 1867 Dr. Hellmuth was made rector of St. Paul's Cathedral and Dean of Huron. He used his large private means unsparingly in advancing the cause of higher education. In 1869 he launched the Hellmuth Ladies' College.
The venerable Canon Christopher, rector of St. Aldate's Church, Oxford, thus alludes to this institution:—"He found that Canadian Protestants were sending their daughters to convent schools, because they did not know of any good Protestant ladies' school. He established an excellent school for young ladies near his own house. I addressed nearly a hundred young ladies in this school in 1872. Some of these had to travel twelve days and nights from their homes to their school, in the absence of a railway from British Columbia."
Dr. Hellmuth was chosen on July 19, 1871, by a large majority of the diocesan synod to be Bishop Coadjutor of Huron, with the title of Bishop of Norfolk and the right of succession. Dr. Cronyn died in the following September, and Dr. Hellmuth became Bishop of Huron. He had been consecrated in St. Paul's Cathedral, London, Ontario, on August 24, 1871. In 1877 the Bishop formed a scheme for a Western University in connexion with Huron College, subscribing no less than 10,000 dollars towards it. In the following year he attended the Lambeth Conference, and took confirmations for the Bishop of London in Norway, Sweden, and Denmark. He came to England again, in 1880, to obtain funds for the Western University, which was opened on October 5, 1881, with a medical faculty in connexion with it. By 1881 the Bishop's exertions had proved so successful that the S.P.G. aid was no longer required, and the diocese could rely on its own resources.
During the Bishop's episcopate, which lasted from 1871 to 1883, great progress was made in every department of diocesan work. The number of livings increased from 34 to 65; the number of churches from 149 to 207; and the clergy from 92 to 135. The Sunday schools rose from 110 to 166; and the communicants from 4,390 to 8,910. Dr. Langtrey, in his "Colonial Church Histories,"[14] says that the Bishop "devoted himself with great earnestness to his work, and soon became very popular throughout the country." The Rev. Dr. Hurst, a resident of twenty years in Huron, thus referred to the Bishop's labours:—"I can speak from personal knowledge of his liberality, zeal, and self-denying efforts to make his diocese an active mission field, and a model for higher Christian education—much at his own personal expense—in both of which God greatly blessed his instrumentality. His indefatigable and successful labours have been acknowledged by all parties in the Church."[15]
The Bishop resigned the see of Huron in 1883 under somewhat peculiar circumstances. The Bishop of Ripon (Dr. Bickersteth) desired to have Dr. Hellmuth appointed his Suffragan under the Act of Henry VIII. Dr. Hellmuth, being informed that his title was to be Bishop of Hull, and that the letters patent could not be executed till he had resigned the see of Huron, formally resigned that see on March 29, 1883.
In his last charge, delivered before the Synod of the Diocese, the Bishop's broad and loving sympathies found vent in the following expressions:—"I am fully persuaded, as I said on a former occasion, that the glory of the Church is her assimilation to Christ. And never will her usefulness and her splendour reach their meridian until the love of a common Saviour shall bind together every heart and unite every hand. Envy, jealousy, evil surmisings and uncharitableness can only tend to weaken and scatter the resources of the Church and palsy her exertions; but, when through the abundant outpouring of the Holy Spirit, arm shall be linked to arm, and heart to heart, and prayer to prayer,—when to love and serve Christ, and to anticipate heaven, and to save immortal souls,—when these shall be the grand and all absorbing terms of Christian communion,—oh, then, what a firm and powerful phalanx shall go forth from the Church of the living God against the powers of darkness and the enemies of men! For this oneness of aim I would again repeat, Pray, strive and labour."
The news of the Bishop's resignation was received with great regret throughout the Dominion, and a service of plate was presented to him with an address from the standing committee of the diocese.
On March 21, 1883, the Bishop of Ripon issued a Pastoral to his diocese, in which he formally announced the Royal assent to the appointment of Dr. Hellmuth as Bishop Suffragan of Hull. In the following May, nearly two months after Dr. Hellmuth's resignation of the see of Huron, the law officers of the Crown discovered that the Act of Henry VIII. did not apply to any one already in Episcopal orders, and that therefore Dr. Hellmuth could not become Bishop Suffragan of Hull. Bishop Hellmuth, who was thus placed in an extremely anomalous position, appealed to the then Governor-General of Canada, Lord Lorne (the present Duke of Argyll), who made representations to Mr. Gladstone, at that time the Prime Minister. In reply, Mr. Gladstone pointed out that the Bishop of Ripon still intended to avail himself of Dr. Hellmuth's services as his Assistant Bishop or Bishop Coadjutor. Bishop Hellmuth then took up his work in the diocese of Ripon as Assistant Bishop, although the position was obviously very different from what he had been led to expect when he resigned the see of Huron. With the consent of Bishop Bickersteth, further representations were made to Mr. Gladstone, who replied expressing regret for the error which had been committed. By the death of Bishop Bickersteth, in 1884, Dr. Hellmuth's position became still more trying, for his commission as Bishop Coadjutor ceased, and he made another appeal to Mr. Gladstone for some suitable preferment, but without success. He was rector and rural dean of Bridlington from 1885 to 1891, and perpetual curate of Bessingby from 1888 to 1891. In the latter year the Colonial and Continental Church Society gave him the chaplaincy of Holy Trinity, Pau, which he held for six years. He was subsequently rector of Compton-Pauncefoot, Somerset, from 1897 to 1899, when he retired owing to failing health. He passed away within two years, on May 28, 1901, at the advanced age of eighty-one.
Bishop Hellmuth was the author of "The Biblical Thesaurus" (1884), a literal translation and critical analysis of every word in the original languages of the Old Testament, with explanatory notes and appendices; and "The Divine Dispensation," a critical commentary on the Hebrew Scriptures. Amongst his minor contributions to literature may be mentioned two articles in "The Everlasting Nation"; one on "The Authenticity and Genuineness of the Pentateuch," (1867) and the other on "The Spirit of Prophecy," a luminous paper on the allusions in the Old Testament to the Messiah of his race.
The Bishop married, first, Catherine, daughter of the late General Thomas Evans, C.B., who died in 1884, and secondly, in 1886, Mary Louisa, second daughter of Admiral the Hon. Arthur Duncombe, son of the first Baron Feversham, and widow of the Hon. Ashley Carr Glyn, son of the first Baron Wolverton.
