Matthew Vines recently and repeatedly used slavery as a wedge tactic to justify the acceptance of homosexual "marriage." Slavery is frequently used as a wedge tactic by "progressive Christians."
I'd like to briefly draw attention to a biting irony, here. Slavery and homosexuality are far more analogous than Vines would like to admit.
People who suffer from addictions are enslaved to their addictions, whether it's pornography, gambling, alcoholism, drug abuse, &c.
The same thing is true for active homosexuals. They don't control it–it controls them.
They are in bondage to their homosexual passions. It's all-consuming.
Active homosexuals are often the mirror-image of womanizers: men whose existence is a string of one-night stands. If they're not having sex with a strange woman, they're on the look-out for their next conquest.
It's not coincidental that Scripture compares sin to slavery. You can be more enslaved to a particular sin than literal slavery. Your addiction to a particular sin is psychologically compulsive as well as physically and financially demanding. It never lets up.
