Can I have your permission to open a branch of your church?
I am very much interested in your teachings and your church. I have therefore decided to open a branch of your church. I have been making preparation to perform and I need your authority to enable me to do it. I should, therefore, be grateful if you would kindly assist me to enable me to establish a branch of your church.
Counting very much on your cooperation and early attention.
Thank you very much.
I have no authority in such matters. That comes from Jesus, and that authority has already been given (Matthew 28:18-20). I have no church. Only Christ has a church (Matthew 16:18). Nor do you need anything other than your Bible to teach and establish a congregation of Christ's people (Romans 10:12-17).
