Methodists have given their ordained ministers a wide latitude of beliefs since WWI. But since their seminaries have become so liberal, you get a minister like the one who trained Hillary Clinton.
Methodists very specifically did not ordain women as elders until after about 1955 or 1960. Since then, the whole denomination has become left-handed. IMHO
Actually, our standards in the area of homosexuality have been written down and are strict. They say that homosexuality is incompatible with Christian teaching and that homosexuals are not to be ordained and that homosexual weddings are not to be performed in our churches.
This is what the conservative wing of the church has won on maintaining for years now, and this is what the admission of the African churches to full voting rights will make extremely difficult for the liberals to change. Last quadrennium they tried an end around to have each national church become their own rule-making organization, but that, too, was defeated.
So, while I readily admit that our seminaries are infected with gross liberalism, I'll also point out that Asbury Seminary, a general Methodist seminary but acceptable to our denomination, has remained biblical, and I'll also point out that a rebellion of sorts has taken place at United Seminary in Dayton, Ohio, and that it has rejected its liberal past and is returning to a more biblical position.
Those who know of these struggles should pray for the conservatives in the United Methodist Church. They are showing progress on some significant fronts.
