The Assembly's first meeting began with a sermon by William Twisse in the nave of Westminster Abbey on 1 July 1643. The nave was so full that the House of Commons had to send members ahead to secure seats. Following the sermon, the divines processed to the Henry VII Chapel, which would be their place of meeting until 2 October when they moved to the warmer and more private Jerusalem Chamber. After their initial meeting they adjourned for about a week, as Parliament had not yet given specific instructions.
