[3] Francis Charlett, rector of Great Brickhill, Buckinghamshire, died in 1653; Mead hoped to succeed him, but the patron, John Duncombe, presented Thomas Clutterbuck.
Clutterbuck resigned his title, and Duncombe, in July 1655, presented Robert Hocknell, whom the 'commissioners for approbation' (triers) rejected, putting in Mead by aid of a troop of horse.
After some violent proceedings, the matter was compromised by Duncombe's agreeing to present William Peirce, a nephew of Hugh Peters.
Shortly after Greenhill's death he was called (13 October 1671) to succeed him as pastor, and was ordained on 14 December 1671 by John Owen, Joseph Caryl, and two others.
In 1674, a meeting-house (opened 13 September) was built for him at Stepney; its roof was upheld by four round pine pillars, presented to him by the States of Holland; above the ceiling was an attic with concealed entrance, a hiding-place for the congregation in troubled times.
In December 1682 Sir William Smith with a strong guard invaded his meeting-house, pulled down the pulpit, and broke up the forms.
In June 1683 Mead was apprehended on suspicion of complicity in the Rye House Plot, and brought before the privy council, where the king ordered his discharge.
Pleading there on one occasion on behalf of poor ministers, he got a collection of £300., ladies putting their rings and watches into the plates.
[3] After the Glorious Revolution, galleries were built (25 March 1689) in his meeting-house, and the adjoining residence and garden were settled (16 July) by the congregation on Mead and his heirs.
On the rupture of the union (1694) over the alleged heresies of Daniel Williams, Mead took a moderate part, but remained in the Pinners' Hall lectureship when the presbyterians seceded.
