and the regent of the Netherlands, both of whom had been requested to deliver him to Henry VIII. After a short stay in the territory of the Prince-bishop of Liège he returned to Rome in August 1537.[37] But though the rebellion in the north had been suppressed, it was sufficiently grave to show Henry the danger incurred at home by religious innovations, while the legatine mission of Cardinal Pole made it advisable to prove to the Catholic rulers of Europe that England had not gone over to the Lutheran camp. The greatest objection taken by the conservative party in England to the /Ten Articles/, drawn up by the king and accepted by Convocation in the previous year (1536), was the absence of express reference to any Sacrament except Baptism, Penance, and the Eucharist. At the meeting of Convocation (1537) the battle was waged between the Catholic-minded bishops let by Tunstall of Durham and the Lutheran party let by Cranmer. At last the other four Sacraments were "found again," and a settlement agreeable to both parties arrived at and embodied in a treatise known as /The Institution of a Christian Man/. It consisted of four parts, the Apostle's Creed, the Seven Sacraments, the Ten Commandments, and the Our Father and Hail Mary. Two separate articles dealing with justification and purgatory taken from the Ten Articles previously issued were appended. The bishops submitted /The Institution/ to the judgment of the king, inviting him as supreme head of the Church to correct whatever was amiss with their doctrine, but Henry, anxious to hold himself free to bargain with the Lutheran princes if necessary, refused to take any responsibility for the work beyond ordering that it might be read in the churches for three years. Hence it was called the /Bishop's Book/.[38]
