China seems to have a forced schism. The government doesn’t allow the Vatican to select bishops, instead appointing its own. I am sure they are ordained (presumably validly) by other bishops of the government-approved church.
There also is an underground church that is loyal to the Magesterium.
What would be interesting to know is whether a Catholic tourist would need to try to find one of the underground churches (which would potentially expose them to harm) or the tourist might fulfill the obligation by attending the state-approved church (presumably refraining from Communion since they are in schism) or be excused from the obligation (due to the difficulty in finding a church in Communion with Rome).
I have some experience with this matter, having lived in and frequently visited China. Although the situation in China is “schism-like”, I have never seen any Church official or document describe it as a formal “schism”. That said, there absolutely are bishops who were appointed by the Chinese government who have not received papal approval and whose communion with the See of Rome is uncertain at best. It is almost impossible for a lay person to determine whether any given bishop is licit and in union with Rome.
First and foremost, if you are visiting China,
do not under any circumstances seek out the “underground” Church. The last thing Chinese Catholics need is a foreigner drawing the attention of the authorities. There is no canonical reason you need to attend an “underground” mass, and you will only be putting yourself and, more importantly, our Chinese brethren in danger.
When I last traveled to China, the advice I received from my parish was that I did not need to attend mass at the “official” government (CCPA) church, because of the unknown status of their communion (no dispensation necessary). Attending a church that is illicit may give people (Chinese or foreign) the impression that “regular” Catholics “approve” of their status, are indifferent to it, or that there is no real distinction between a licit and illicit bishop. That said, I was also told that if I wanted I could attend, and ultimately the decision was mine. I did not ask about receiving the Eucharist, since I did not plan to receive anyway (due to the uncertainty mentioned above). My personal advice is, do not receive unless you are sure the bishop is in communion with Rome; but in any case the Eucharist is valid, even if the Bishop is illicit. If you are in danger of death or conscious of a mortal sin, I personally would seek out any Catholic priest, licit or illicit, to hear my confession.
Ultimately, talk to your priest/parish office about it, be respectful of Chinese laws whether you attend a CCPA church or not, and pray for the situation in China.
