He also said that "in the Byzantine, Ukrainian, Russian, and Greek Catholic Churches [...] the priests can be married, but the bishops have to be celibate". He said that many of those in Western Catholicism who are pushing for more discussion about the issue do so from a position of "pragmatism", based on a loss of manpower. He states that "If, hypothetically, Western Catholicism were to review the issue of celibacy, I think it would do so for cultural reasons (as in the East), not so much as a universal option." He emphasized that, in the meantime, the rule must be strictly followed, and any priest who cannot obey it "has to leave the ministry."
