The Marriage: Beauty and the Beast

As a father is to the ecumenical movement, what would Dr. Martin Luther say to Mr. Papacy and Miss Protestant about this proposed marriage?  Based on "Sola Escritura," we are told in 2 Corinthians 6:14 that we are not to be unequally yoked.  On the other hand, come take a closer look at what the Beast is proposing to the Bride.  Is he proposing peace and security at the expense of forsaking the truth?  May it be that this Beast is really a wolf dressed in sheeps clothing?  Note that not everyone who says "Lord, Lord" will enter into the Kingdom of Heaven.
