In 1570, at the request of Edmund Grindal, Bishop of London, John Foxe preached a sermon at PaulÕs Cross, which was an open-air pulpit {on the grounds of St. PaulÕs Cathedral} of mostly timber with room for 3 or 4 inside it, set on stone steps with a lead-covered roof and a low surrounding wall. From here was preached much of the English Reformation, with sermons preached here usually printed and thus redistributed to a wider audience. This lofty exposition of the Protestant doctrine of redemption and attack on the doctrinal errors of the Papist Church was enlarged and published that year as A Sermon of Christ Crucified. ÒTo know the crucified sacrifice of ChristÕs body to be a perfect deliverance of all his people, to be a full satisfaction once, and for ever, for all our sins - to be a free justification, redemption, and righteousness before God for ever, to all them that believe in him, without any other means or help adjoined to him - this is to know Christ Jesus crucified.Ó Foxe.
