Yes. It is an infallible decision concerning a secondary object connected with and necessary for the defence of revealed dogma. We have to accept the decision, not from a motive of divine faith, but because of the infallible authority of the Church. The question was submitted to a thorough and even sympathetic consideration, the Pope knowing that if Anglican Orders could be admitted as valid the road to re-union would be much easier. But the evidence compelled the Pope to declare them invalid. Pope Leo XIII. definitely adopted the decision of die appointed Commission, and published the condemnation with his own infallible authority to support it. No Anglican clergyman could officiate in the Catholic Church without being ordained by a Catholic Bishop.
