3. A benefice in which there are both rector and vicar, in which case the duty commonly rests with the vicar, and the rectory is called a sinecure; but no church in which there is but one incumbent is properly a sinecure.
A church may be down, or the parish become destitute of parishioners; but still there is not a sinecure, for the incumbent is under an obligation of performing divine service if the church should be rebuilt or the parish become inhabited.
