Here is an idea for the Church to trump the perverts.
Stop doing marriages & start doing “Christian unions between a man & a woman”, & call it that.
Stop sanctioning marriage, which has become meaningless. Let marriage be a solely government institution, bereft of an religious or spiritual meaning, much like a fishing license.
Create a new institution within the church joining together one man & one woman, until death do them part - no divorce possible, in a spiritual union recognized by the church, & limited to church members in good standing only.
If the couple wants to have a civil union too for tax purposes, that’s fine, but it has no relation to the Christian Union in the eyes of the Church & is meaningless to the Church.
Leave the perverts with their temporary, meaningless, secular unions they so deserve.
Change a few words & the Church can take back the meaning & purpose of marriage, while completely excluding the opinion of the bureaucrats.
I agree with your comment that Christians need to rename and redefine what a Christian marriage actually is. Civil unions are formed for various legal reasons, they confer employment benefits and tax status, and they provide a form of self esteem to gay persons. A Christian marriage such as you described would provide spiritual value to Christians who submit to this form of marriage. Married Christians would provide salt and light to all who witness their marriages. The onus would be on all Christian married people to set as perfect examples as possible.
Maybe if more “Christians” lived up to their vows in the first place, we wouldn’t be in this mess.
Good idea.
