That’s Christlike? What you’re implying by saying so is that people not buying your legalistic mindset are false teachers. Do you have such authority?
Yes I do.
Through the indwelling Holy Spirit who teaches me both of God's righteousness and opens my heart and mind to
the scriptures.
When you go to a gay "wedding" you are joining in on a Satanic corruption of what has been God given - marriage between a
man and a woman - as a Christian you ought not to partake of the works of darkness.
You are supposed to walking in the light. This requires a bit more wisdom and discernment than just being "nice" to sinners.
For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God
in the face of Jesus Christ.
2Corinthians 4:6
14 Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?
2Corinthians 6:14
6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.
7 Therefore do not become partners with them;
8 for at one time you were darkness, but now you are light in the Lord. Walk as children of light
Ephesians 5:
