I agree. When we compromise our faith to change the world it is us, not the world, that changes.
I don't know the answer to your last question.
The problem is politics IS compromise. It has to be in the US because we have a government of the people.
Would it be right to legislate Christian values on a nation that is a Christian minority? That is what we are ultimately talking about.
And holding office means that you have to make compromises to get less of what you want.
The GOP did that with SSM. They realized that they needed the LGBT conservatives vote. They did that with abortion.
Politics is give and take, so you have to be willing to give (often on moral issues) to get some of what you want.
And you are a part of a party that supports evil.
So my answer is I couldn't hold office because that'd be too great a compromise.
But each of us will be held accountable for our actions and voice. So each of us have to make our own decision.
I can't support:
1. Same sex marriage
2. A dedication to representing LGBT conservatives and their interests
3. Trump's vow to keep abortion on demand abortion choice for the people.
So I will not vote. There is nothing good in the platform that woukd make me support those evils.
@Van has no problem supporting those evils for the possibility of the government partially funding private schools.
We each have to look at what we support and make up their own minds.
