Part of the problem with the Anglican Ordinal was the omission of the porrection of the instruments, a part of the rite that gave clarity to the Catholic understanding of priestly ordination.
Ordinands were given a chalice and paten, and the bishop stated that they were being given authority to offer Masses for the quick and the dead. Their hands were annointed with chrism. These acts were omitted in the Ordinal because there was a desire to deny the sacrifical nature of the Eucharist and the priesthood. In fact, soon after, the 39 Articles of the Church of England explcitly denied this, as well as transubstantiation and many other aspects of the Catholic faith. All of this resulted in, among other things, the excommunication of Elizabeth I in 1570.
Now, before others bring it up, I am aware that some (but not all) High Church Anglicans began to include these ceremonies in their ordinations beginning in the early 20th century (after Apostolicae Curae). I am also aware of the participation of Old Catholic bishops in some (but certainly not all) Anglican ordinations (primarily of bishops–few priests had this happen), the so-called “Dutch Touch” for High Church ordinations, beginning in the WWI era. However, the succession had already, and long before, been broken.
I am also aware of the response of the Archbishops of Canterbury and York in 1897, Saepius Officio, which pointed out that several parts of the modern Roman ordination rite, including the porrection of the instruments, had not existed in the earliest sacramentaries of the Church. The Anglican archbishops, therefore, objected to this criteria applied by Pope Leo XIII. However, the issue with the removal of these important parts of the rite is the intent of their deletion from the rite–and therefore the intent of the bishops performing the ordinations.
These rites were removed precisely because they unambiguously demonstrated the Catholic doctrine of the sacrificial nature of the Mass and of the priesthood. The priest’s hands are holy precisely because with them he offers the Holy Sacrifice of the Mass, which is the same Sacrifice as that of Calvary. The Anglican Ordinal intentionally hedged on this sacramental understanding. Moreover, the 39 Articles and countless sunbsequent events of history made quite apparent the influence of Calvinism, and that the Ordinal clearly did NOT intend what the Catholic Church had done for centuries. It is one thing when the patristic rites had not yet developed these aspects of the ordination ritual; it is entirely another matter when, after centuries of carrying them out, a new form deliberately removes them because it doubts the nature of the priesthood. And until the Oxford Movement of the 19th century, Anglican liturgy, with its infrequent celebrations of “Holy Communion” reflected this newer belief. (The term Mass was not used again until the Movement, and even then only by those who called themselves Anglo-Catholics.). Even after the Movement, Anglican forumulas were (and remain) ambiguous enough to allow either a Catholic or Protestant interpretation.
