Revision of the Liturgy, although occasionally discussed, cannot be said to have been an eighteenth-century question. Subscription, on the other hand, as required by law to the Thirty-nine Articles, received a great deal of anxious attention. This was quite inevitable. Much had been said and written on the subject in the two previous centuries; but until law, or usage so well established and so well understood as to take the place of law, had interpreted with sufficient plainness the force and meaning of subscription, the subject was necessarily encompassed with much uneasiness and perplexity. Through a material alteration in the law of the English Church, the consciences of the clergy have at last been relieved of what could scarcely fail to be a stumbling-block. By an Act passed by Parliament in 1865, and confirmed by both Houses of Convocation, an important change was made in the wording of the declaration required. Before that time the subscriber had to 'acknowledge all and every the Articles ... to be agreeable to the word of God.'[413] He now has to assent to the Articles, the Book of Common Prayer, and of the ordering of priests and deacons, and to believe the doctrine therein set forth to be agreeable to the Word of God. The omission of the 'all and every,' and the insertion of the word 'doctrine' in the singular, constituted a substantial improvement, as distinctly recognising that general adhesion and that liberty of criticism, which had long been practically admitted, and in fact authorised, by competent legal decisions, but which scarcely seemed warranted by the wording of the subscription.
