From the order for ordination of elders in The United Methodist Book of Worship:
In covenant with other elders, will you be loyal to The United Methodist Church, accepting its order, liturgy, doctrine, and discipline, defending it against all doctrines contrary to God’s Holy Word, and accepting the authority of those who are appointed to supervise your ministry?
I will, with the help of God
From the order for admission into full membership of the annual conference:
Have you studied the doctrines of The United Methodist Church?
I have studied them.
After full examination, do you believe that our doctrines are in harmony with the Holy Scriptures?
I believe that they are.
Will you preach and maintain them?
To the best of my ability, I will.
When I read these words that I one day may say before God and the church, I think of other vows I have taken. I think of my baptismal vows. Those are vows that I cannot renounce or ignore without renouncing my baptism. I think of my marriage vows. Those are vows I cannot decide no longer bind me without breaking faith with my wife.
Is it any more demanding to ask that I maintain fidelity to my marriage and my baptism than it will be one day to ask that I stay true to my ordination vows, if the Lord grants me the opportunity to make them?
