Thomas Lambe (also spelt Lamb) was the leader of one of the early Baptist churches of Christ in England, and an influential figure, both in terms of practice and belief. He is commonly referred to as the "soap boiler".
Lambe's birth date is unknown, but it was in the early years of the seventeenth century. Records of his activities exist from 1629 onwards, at which time he was living in St Giles in Colchester with his wife and eight children.
From 1629-1639 he was frequently in trouble with the Archdeacon's Court in Colchester for preaching outside of the bounds of the Church of England during the time that the Archbishop of Canterbury, William Laud was seeking to impose uniformity upon the churches in England. This was to continue throughout his ministry as he was frequently arrested and imprisoned.
His Separatist views developed into distinctly beliefs and practices of churches of Christ during the 1630s and by 1640 was leading a congregation of New Testament Christians meeting at Bell Alley in Coleman Street, London (along with Samuel Oates and Henry Denne). This church is also referred to as the Coleman Street Church of Christ. He was soon arrested and imprisoned for four months and was released on bail 25 June 1640 , with the injunction "not to preach, baptize or frequent any conventicle."
The meetings in Coleman Street were open to the public and reported as being lively: "Many used to resort to this church and meeting, the house, yards full, especially young youths & wenches flock hither and all of them preach universal redemption. In their church meetings and exercises there is such a confusion & noise as if it were a play." This church was successful and was described in 1647 by Robert Baillie in a tract against such churches as "Mr Lamb's (sic) congregation, the greatest as they say, and most fruitful of all their societies without comparison."
He travelled extensively across England preaching, baptising and planting churches, for example in Gloucestershire in December 1641 where he preached at Cranham and "subverted many. And shortly after, in extreme cold, and frosty time, in the night season, diverse men and women were rebaptised in the Severn by Gloucester."
