"What is a church? Is it not a company of sinners gathered together, according unto God's appointment, to give glory and praise to him for pardoning grace, for the forgiveness of sins, and to yield him that obedience which he requires from us on the account of his having so dealt with us? This is the nature, this is the end of a church. He that understandeth it not, he that useth it not unto that end, doth but abuse that great institution. And such abuse the world is full of."
