If the body were all eye, where would hearing be? If the body were all ear, where would smell be?
The eye cannot say to the hand, 'I have no need of you,' nor again the head to the feet, 'I have no need of you.'
Are all apostles? Are all prophets? Are all teachers? Are all workers of miracles?
If the ear were to say, 'Because I am not the eye, I do not belong to the body,' that does not make it no part of the body.
As it is, God has set the members in the body, each as it pleased him.
