a truth to be "held definitively, but are not able to be declared as divinely revealed," as stated in a commentary by the Congregation for the Doctrine of the Faith. Cardinal Basil Hume explained the conditional character of his ordination of Graham Leonard, former Anglican bishop of the Diocese of London, to the priesthood in the following way: "While firmly restating the judgement of Apostolicae Curae that Anglican ordination is invalid, the Roman Catholic Church takes account of the involvement, in some Anglican episcopal ordinations, of bishops of the Old Catholic Church of the Union of Utrecht who are validly ordained. In particular and probably rare cases the authorities in Rome may judge that there is a 'prudent doubt' concerning the invalidity of priestly ordination received by an individual Anglican minister ordained in this line of succession." At the same time, he stated: "Since the church must be in no doubt of the validity of the sacraments celebrated for the Roman Catholic community, it must ask all who are chosen to exercise the priesthood in the Catholic Church to accept sacramental ordination in order to fulfill their ministry and be integrated into the apostolic succession." Since Apostolicae curae was issued many Anglican jurisdictions have revised their ordinals, bringing them more in line with ordinals of the early Church. Timothy Dufort, writing in The Tablet in 1982, attempted to present an ecumenical solution to the problem of how the Roman Catholic Church might accept Anglican orders without needing to formally repudiate Apostolicae curae at all. Dufort argued that by 1969 all Anglican bishops had acquired apostolic succession fully recognized by Rome, since from the 1930s Old Catholic bishops (the validity of whose orders the Vatican has never questioned) have acted as co-consecrators in the ordination of Anglican bishops. This view has not yet been considered formally by the Holy See, but after Anglican Bishop Graham Leonard converted to Roman Catholicism, he was only reordained in 1994 because of the presence of Old Catholic bishops at his ordination. The question of the validity of Anglican orders has been further complicated by the Anglican ordination of women. In a document it published in July 1998, the Congregation for the Doctrine of the Faith stated that the Catholic Church's declaration on the invalidity of Anglican ordinations is a teaching that the church has definitively propounded and that therefore every Roman Catholic is required to
