The Vatican stepped up its battle with the Chinese Catholic Church this weekend, excommunicating a bishop who was ordained during the week without the pope's permission.
Pope Benedict XVI "deplored" the "illicit" ordination of the Rev. Joseph Huang Bingzhang and expelled him from the church because he was "ordained without papal mandate," the Vatican said Saturday.
He was the second bishop ordained by Chinese Catholics without Vatican permission in the past month, and at least the third in the past year, as Beijing and Rome struggle over control of the Catholic Church in China.
Huang Bingzhang was ordained as Bishop of the Diocese of Shantou in southeast China on Thursday, the Vatican said, although Rome had asked him "on numerous occasions not to accept episcopal ordination."
