Can you be confirmed twice?
If a person has been confirmed, then they are members of the church and have made their profession of faith. Certainly a pastor and church can urge that anyone coming to the local church to become a member participates in an orientation to the new local church. However, when anyone becomes a professing member of a local church, he or she is a professing member of The United Methodist Church and of the universal church of Jesus Christ. No further ritual action is required, except for reception in the local church pledging to support it with their prayers, presence, gifts, service and witness.
I do not think it is appropriate to "require" being "confirmed again" as that calls into question the confirmation that has already taken place. Pastors and churches rightly invite and encourage reaffirmation of the baptismal covenant and profession of faith. It cannot and should not be required. Pastors and local churches are part of a connectional church--what happened in one United Methodist church happened in all of the United Methodist churches.
