He was born in
Cottenham, Cambridgeshire, the son and grandson of Anglican clergymen, who were both named John Tenison; his mother was Mercy Dowsing. He was educated at
Norwich School, going on to
Corpus Christi College, Cambridge, as a scholar on Archbishop
Matthew Parker's foundation. He graduated in 1657, and was chosen fellow in 1659. For a short time he studied medicine, but in 1659 was privately ordained. As curate of
St Andrew the Great, Cambridge from 1662, he set an example by his devoted attention to the sufferers from the
plague. In 1667 he was presented to the living of
Holywell-cum-
Needingworth, Huntingdonshire, by the
Earl of Manchester, to whose son he had been tutor, and in 1670 to that of
St Peter Mancroft, Norwich. In 1680 he received the degree of Doctor of Divinity, and was presented by King
Charles II to the important London church of
St Martin-in-the-Fields. Tenison, according to
Gilbert Burnet, "endowed schools including
Archbishop Tenison's School, Lambeth, founded in 1685 and
Archbishop Tenison's School, Croydon, founded in 1714, set up a public library, and kept many curates to assist him in his indefatigable labours". Being a strenuous opponent of the Church of Rome, and "
Whitehall lying within that parish, he stood as in the front of the battle all King James's reign". In 1678, in a
Discourse of Idolatry, he condemned the heathenish idolatry practised in the Church of Rome, and in a sermon which he published in 1681 on
Discretion in Giving Alms was attacked by Andrew Poulton, head of the
Jesuits in the Savoy. Tenison's reputation as an enemy of Romanism led the
Duke of Monmouth to send for him before his execution in 1685, when Bishops
Thomas Ken and
Francis Turner refused to administer
holy communion; but, although Tenison spoke to him in "a softer and less peremptory manner" than the two bishops, he was, like them, not satisfied with the sufficiency of Monmouth's penitence. Under King
William III, Tenison was in 1689 named a member of the ecclesiastical commission appointed to prepare matters towards a reconciliation of the Dissenters, the revision of the liturgy being specially entrusted to him. A sermon he preached on the commission was published the same year. He strongly supported, at least in public, the
Glorious Revolution, though not without some private misgivings, especially concerning the ejection of Archbishop
William Sancroft and the other "non-juring" bishops.
Henry Hyde, 2nd Earl of Clarendon in his diary records some frank remarks made by Tenison on this subject at a dinner party in 1691: That there had been irregularities in our settlement; that it was wished that things had been otherwise, but that we were now to make the best of it, and support this government as it was, for fear of a worse. He preached a
funeral sermon for
Nell Gwyn in 1687, in which he represented her as truly penitent – a charitable judgment that did not meet with universal approval. The general liberality of Tenison's religious views won him royal favour, and, after being made
Bishop of Lincoln in 1691, he was promoted to Archbishop of Canterbury in December 1694. appointed to administer the kingdom whilst he was on campaign in Europe. ==Archbishop of Canterbury==
