The custom of the reservation of the Sacrament is, as is well known, of great antiquity.  cf. Justin Martyr, Apol. i. 85; Tertull., De Orat. xix. and Ad Ux. ii. 5; S. Cyprian, De Lapsis cxxxii.; Jerome, Ep. cxxv.  Abuses of the practice soon led to prohibition.  So an Armenian Canon of the fourth century (Canones Isaaci, in Mai, Script. Vet. Nov. Coll. x. 280) and the Council of Saragossa, 380; though in these cases there seems an idea of surreptitious reservation.  On the doctrine of the English Church on this subject reference may be made to the Report of a Committee of the Upper House of the Convocation of Canterbury in 1885. The Rubric of 1549 allowed reservation, and it does not seem to have been prohibited until 1661.  Bishop A. P. Forbes on Article xxviii. points out that in the Article reservation is not forbidden, but declared not to be of Christ’s institution, and consequently not binding on the Church.  The distinction will not be forgotten between reservation and worship of the reserved Sacrament.
