I want to be very careful here but this is actually an interesting question. Clearly if by “the bishops”, is meant “all the bishops”, then the answer would be no. Is it unreasonable to ask, however, whether the proposal that some sexually active couples in irregular unions should be allowed to receive communion is a heresy? On the face of it it would appear so (unreasonable), since a seemingly large number of bishops apparently support this proposal, not to mention the fact that (it is alleged) the pope wants the question addressed. Those answers are not satisfactory.
That bishops have supported heresies in the past disproves the assertion that a bishop’s support for a proposal means it cannot be heretical. As to whether the pope has specifically requested that this question be addressed (again), color me doubtful. This has been asserted but I have yet to see it documented. I’ll believe it when I see it.
Here is the church’s definition of heresy:*(CCC 2089) Heresy is the obstinate post-baptismal denial of some truth which must be believed with divine and catholic faith, or it is likewise an obstinate doubt concerning the same
*The pope has already stated that the doctrines involved in this issue will not be changed, and if that is the case then there can be no heresy since nothing that must be believed will be altered. This leaves the question unanswered: if the doctrines do not change then how can someone be admitted to communion tomorrow who is doctrinally forbidden from receiving today? I understand that the “answer” to this question is that some “disciplines” may be altered, but no one has even suggested what discipline could be modified to get around a doctrinal prohibition.
That being the case, it does not seem unreasonable to suspect that it is the doctrines that are being targeted for “modification”…which returns us to the question of whether the belief that one or more doctrines needs reversing constitutes heresy.
