It is too late for the Methodist church (as with Episcopalians and their heretical brethren). All of the "confessing" movements and attempts to turn things around are unlikely to succeed. Once a denomination starts down the road of compromise, caring more about what the world thinks than what God requires, it is nearly impossible to bring it back. Only Southern Baptists in modern times have succeeded in reversing a liberal trend, but not without a bruising fight.
The only course for people who still care what God thinks is to follow the instructions of Paul the Apostle: "Come out from among them and be separate." John Wesley believed in absolutes that those who claim him as their spiritual ancestor have abandoned. He wrote: "But the Christian rule of right and wrong is the word of God, the writings of the Old and New Testament; all that the Prophets and 'holy men of old' wrote 'as they were moved by the Holy Ghost'; all that Scripture which was given by inspiration of God, and which is indeed profitable for doctrine, or teaching the whole will of God; for reproof of what is contrary thereto; for correction of error; and for instruction, or training us up, in righteousness" (a reference to 2 Timothy 3:16).
Dammann isn't the first lesbian ordained in the Methodist Church, but she should be the last tolerated by church members who are faithful to something higher than the shifting winds of cultural change. At the Methodist church trial, a majority of jurors failed their God and Methodism's founder. They have lost their authority to speak for God or to man on God's behalf. Methodists would be well advised to seek a denomination where God and not man is the supreme authority.
