1 Corinthians 5:4

In the name of our Lord Jesus] Placed emphatically at the beginning, to indicate the Church's final authority for taking this step to enforce discipline: cp. Matthew 18:18; Matthew 18:20. When ye are gathered together, etc.] St. Paul did not take discipline out of the hands of the Church. He stepped in when the Church had failed in duty, pointing out the duty and leaving the Church to perform it.

My spirit] They were to think of him as present in spirit, and to let his influence mould their deliberations.
