Using Protestant logic... We have no way of identifying who a Pastor is... Or what a genuine marriage is... All is subject to personal interpretation once the concept of authority is removed.
using Catholic logic I can pay for divorce and its not a divorce.
We don't know who a 'pastor' is for sure - that is why it is so easy for us to vote with our feet. That is why a church is nothing but a gathering place. As that gathering starts to promulgate non-scriptural things, we dust off our feet, and go where the Gospel is being preached.
And the Bible differs from y'all in what a marriage is anyway, so what value has your authority in that? In the Bible, marriage is formally contracted (written agreement), followed by a separation while the groom goes to 'prepare a place for her', followed by the consummation, followed by public presentation. It is the agreement between the two, and the consummation that are the efficacious part - they are bound together BEFORE any vows or public act. The authority of a priest is superfluous, at best.
Likewise, a bill of divorcement is accomplished without any intercession or permission by religious authority.
So the authority you claim is not there... in either place.
