They do, ignoring Jesus' command that what God had joined, let no man break asunder. That doesn't change the teachings of Christ that divorce and remarry is adultery. That just makes it a more acceptable sin in the eyes of the church in question.
Also, we are talking about a recreational sex behavior. Refusing to celebrate homosexual sex at a funeral is no different than refusing to celebrate a dead persons sex with animals or sex orgies when going to club med’s hedonism(tm) resorts.
We're talking about a church refusing to conduct a funeral because they believe to do so promotes a sinful lifestyle, making it clear that some sinful lifestyles are OK for them and others are not.
You are incorrect. Not to question your church faith, however there are provisions which allow for ecclisiastical divorces under orthodoox teachings. (but then again they do go by the untranslated original text new testament) The marriage is not an equivalent to a lifestyle based on mere hedonistic sexual recreation.
as for the funeral, you are making it to big. focus. it is really simple. If the family did NOT make a focus of the homosexual conduct of the person, the funeral would have gone forward. The homosexual life partner and the family refused to give proper dignity and respect to the church. They saw it as a mere building for hire not as a place of worship.
