It is well known that the category of the personal is vital to Christian thinking, both in relation to God who is understood to be three-personed and to humanity which is seen as made in God’s image and likeness. Often in common usage what is personal is thought to be identical with what is individual. But the reverse is the case. For whereas when we speak of the individual we speak of each one in his separateness in competition with all others, when we speak of the person we speak of each one in his relatedness, in communion with all others. Indeed just as in God each of the three divine persons lives in and through the others, so also it is at the human level. We are members one of another. In each the whole is present.
