Commenting on the Episcopal Church's decision to change marriage terminology from "husband and wife" to "union of two people," evangelical leader Rev. Franklin Graham said that to "change what God has defined" is "disobedience," sin, and added that "all of this is caving to the gay agenda."

In a May 18 post on Facebook, Rev. Graham said, "I have many friends in the Episcopal Church and I was saddened when I recently learned that the church wants to remove the terms 'husband' and 'wife' from their standardized marital vows. They want to replace the phrase the 'union of husband and wife' with the 'union of two people.'"

"I’ve got news for them -- just changing their words in their ceremony won’t make it right," said Graham. "You cannot change what God has defined."

"Through the centuries, people have tried to reinterpret, repackage, or rewrite God’s laws to suit themselves and their own evil desires," he said. "It’s nothing new; but the end result is always the same. It’s called disobedience—it’s called sin. And sin brings God’s judgment."

"All of this is caving to the gay agenda," said Rev. Graham.

He continued, "I read that the Church of England’s Secretary-General William Nye has been an outspoken critic of this change—good for him. More Christians and more people in church leadership should speak up about the sins that are within the church and stand against things that would not be aligned with the authority of God’s Word. Do you agree?"

He ended his post with the passage from 1 Peter 1:25: "the word of the Lord remains forever."
