While the cardinalate has long been expanded beyond the Roman pastoral clergy and Roman Curia, every cardinal priest has a titular church in Rome, though they may be bishops or archbishops elsewhere, just as cardinal bishops are given one of the suburbicarian dioceses around Rome. Pope Paul VI abolished all administrative rights cardinals had with regard to their titular churches, though the cardinal's name and coat of arms are still posted in the church, and they are expected to celebrate mass and preach there if convenient when they are in Rome.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Each cardinal priest has what?
a titular church in Rome
