No. It’s because masters cannot truthfully make the statement that your present construction of marriage seeks to make: that one person is more special to them than another. This is not a statement that a master makes, and it is not a statement that God makes. The fact is that your marriage vows, as you presently construct them, have you making a very un-Godly statement. It is the height of irony that you feel this is the holiest of holy promises, for it is a promise that God would never make.
