I am indeed happy to reaffirm my deep affection and esteem in our Lord Jesus Christ to all the Catholic sons and daughters of the great and illustrious Chinese family. With all the ardour of my heart I feel spiritually present among them, and I assure them that I am especially close to those who have remained faithful to Jesus Christ and to his Church in the midst of difficulties of all kinds, and have testified and continue to testify, even at the cost of deep and prolonged suffering, that the principle of communion with the Successor of Peter, whom the Lord constituted his Vicar and the ' permanent and visible source and foundation of unity of faith and fellowship' (Lumen gentium, n. 18), cannot be renounced by a Catholic who desires to remain such and to be recognized as such. (John Paul II, Letter to Cardinal Tomko)
The CPA was excommunicated already by Pius XII. If it were to have been founded during this Pope's reign, I am sure he would have excommunicated them.
