Legal civil unions would likely be the easy out. But, it certainly does open the door to "variations" if that becomes the law of the land. From the religious stand point, even that is somewhat of a mix bag as some churches are now allowing gay clergy or priests.
Polgamy is another issue that certainly will get "green lighted" if same sex marriage is allowed. Just don't see anything stopping it. As to whether it is immoral, well......depends on the religion.
Need to point out one thing though Dave.....these Churches are not
The Church. They are simply part of the falling away as foretold, and will be judged accordingly. The real church is not a building, group of worldly people, or even a religious group. The real Church is made of up true believers and followers of the Son of God......and the teachings, commands, and
morality which accompanies.
Not to take offense, but merely pointing out these people who allow the very same things the world condones/tolerates are not, and never were, part of the body of true believers. I think the OP is right in many things he espouses, but
perhaps without the understanding that all these things are to be expected, are going to happen, and there is nothing to stop it.
We are to occupy and stand fast in our belief until The Lord returns. The Christin should be of calm spirit and light of heart, but we do on occasion express alarm over how fast all this is happening. It's described as a women in childbirth and this lawlessness/immorality will increase in both intensity and frequency until in reaches a culmination. We should expect no less and I understand the OP's concern, given the birth pang description.
Rom 10
[17] So then faith cometh by hearing, and hearing by the word of God.
Simply deciphered......We are not going to scare people into conversion, should not be in dismay over the signs of the times, or seek to sound trumpets before those who do not believe. We are to stand bold in our position, hold the line in our house, and be an example of no fear. There is nothing in this world getting any better....it's going to worsen as we go.
