Hoare was noted as an evangelical preacher, and edited The Christian Herald, a prophetical journal that appeared from 1830 to 1835, and was published in Dublin. Its editorial line was historicist and premillennialist. It reported in detail on the first two prophetic conferences at Powerscourt House, and ran some articles by John Nelson Darby. A sequel publication, under the same title, was later started by Michael Paget Baxter. The attitude of The Christian Herald to eschatology had something in common with other periodicals, Churchman's Monthly Review, and The Quarterly Journal of Prophecy, and the views of Thomas Nolan. The central idea was that the personal reign of Christ would be prolonged indefinitely.
Works
Hoare wrote numerous sermons; and other works including:
Practical Observations on Church Reform, the Tithe Question and National Education in Ireland
The Tendency of the Principles advocated in the Tracts for the Times considered. In this work on the Tracts for the Times, cast as advice to a candidate for ordination, Hoare advised against emphasis on the antiquity of the Irish church, as an argument easily subverted to Catholic ends.
The Time of the End; or, The World, The Visible Church, and the People of God, at the Advent of the Lord.
The Duty and Expediency on the Part of the Landed Proprietors of Ireland, of Co-operating with the Board of National Education; Considered in a Letter to a Deputy-Lieutenant of the Co. Sligo
The English Settler's Guide Through Irish Difficulties; Or, a Hand-book for Ireland, with Reference to Present and Future Prospects
Remarks on certain mis-statements as to the extent of scriptural education in Ireland, previous to the establishment of the National System. Hoare was questioned in 1864 about the effect of the National Education System in Ireland, in particular on the financing of the Kildare Place Society, by a House of Lords committee.
