Some churches are too pragmatic and it conflicts with other churches. Some Churches have different beliefs and it impacts with the interpretations for example Reformed and Baptist is little different. Reformed believes God elects and 5 points and the Baptist don't believe in God elects.
Some Churches twist the translations/interpretations and the church who knows the absolute right from the Bible is trying to correct the twisted translations/interpretations. That is how it caused to have a debate with it.
Yeah, You can love everyone but you don't have to have sex with everyone or with same-sex. You only can have sex after you marry with opposite-sex and not with transexual.
Well, I couldn't find a verse with interracial marriage is a sin. It must be a white person that is KKK or can't accept the black family into their family because of white power or something else and more of fears from the black people. Where did the Bible say it is ok to burn the witches? None. You need to remember this many people tends to abuse the Bible for a quick solution because people tends to say ok whenever you said it is said from the Bible! Well, you need to check if it matches what the Bible said then you know what to do. If not then the person is abusing the power from the Bible with you.
The Church did right thing to ask her to leave from their Church. She refuses to repent her sin, homosexual. So The church had to ask her to leave to prevent spreading the sinful life at the Church. Anyway I am narrowing to the point that you stated. She lost her faith and she never had a faith at first place. It is called fake faith. Once you have faith and you will always have the faith until you die.
That Church must be a pragmatic church. They want them because of their money and not to repent them to God. Or the Church is trying to brag the numbers at the Church.
I am not narrow-minded person I am just following the Bible. I know there are many situations but I choose to follow the Bible because the Bible is a perfect plan to follow.
Please read my points about the judging thing.
