How do you address a Lutheran Bishop?

Answer 1

Usually,

Pastor and last name.

In more formal settings it would be Reverend (add last name.)

In a church setting it would be Pastor and last name.

Some pastors will be very informal and use Pastor and then first name.

Some male Lutheran pastors are known as "Father" plus last last name, which is the common address in Europe. Since the ordination of women has been allowed, sometimes female parish pastors are addressed "Mother" plus last (or first) name, but this is largely uncommon in the U.S.

Answer 2

A Lutheran bishop is referred to as the "Right Reverend (Doctor[-if he/she is one] First and Last Name.) When speaking directly to them, call them "Bishop (Last Name.)" Some may give you permission in an informal setting to use their first name. If so, then you may address them verbally as "Bishop (First Name.)"
