Only Rome has the authority to approve an annulment. Once given, it must be accepted.
First of all, this is your opinion and you cannot bind the consciences of others by it. On the contrary, what I said about the sacrament of matrimony is the teaching of the Church, which is taught by the authority of Rome, and
that must be accepted.
Secondly, while this might be a logical statement from a mainstream Novus Ordo practitioner, it makes no sense being used by a traditional Catholic whose religion involves rejecting countless things currently coming from Rome.
