On 18th September, 1896, Pope Leo XIII issued his Encyclical Letter Apostolicae Curae regarding the nullity of Anglican Orders:
"25. But the words which until recently were commonly held by Anglicans to constitute the proper form of priestly ordination namely, "Receive the Holy Ghost," certainly do not in the least definitely express the sacred Ordel of Priesthood (sacerdotium) or its grace and power, which is chiefly the power "of consecrating and of offering the true Body and Blood of the Lord" (Council of Trent, Sess. XXIII, de Sacr. Ord. , Canon 1) in that sacrifice which is no "bare commemoration of the sacrifice offered on the Cross" (Ibid, Sess XXII., de Sacrif. Missae, Canon 3)."
"26. This form had, indeed, afterwards added to it the words "for the office and work of a priest," etc.; but this rather shows that the Anglicans themselves perceived that the first form was defective and inadequate. But even if this addition could give to the form its due signification, it was introduced too late, as a century had already elapsed since the adoption of the Edwardine Ordinal, for, as the Hierarchy had become extinct, there remained no power of ordaining."
"27. In vain has help been recently sought for the plea of the validity of Anglican Orders from the other prayers of the same Ordinal. For, to put aside other reasons when show this to be insufficient for the purpose in the Anglican life, let this argument suffice for all. From them has been deliberately removed whatever sets forth the dignity and office of the priesthood in the Catholic rite. That "form" consequently cannot be considered apt or sufficient for the Sacrament which omits what it ought essentially to signify."
