5人认识身体的头一个证明，就是不能单独。……人还未认识身体之前，他是单独的，他也能单独。他的生活、行动、工作、事奉都是单独的，外表好像和弟兄们在一起，却没有真实的配搭和联络。但等到他在生命里往前去，认识了一点身体，他就看见作基督徒不是单独的，乃是团体的。他若要一直活在主里面，就不能失去身体的交通，也不能离开肢体的配搭。到这时候，基督的身体对于他就是一个实际的东西。他在召会中，就再也不能单独事奉了。他从最深处，感觉需要别人和他一同作基督徒。……没有弟兄姊妹的配搭，就不能工作；没有召会的扶持，也不能生活。到这时候，他就很自然的，和众圣徒配搭成一个身体，而无法分离。所以，凡还能单独的，就是没有认识身体；凡真认识身体的，定规不能单独（李文集一九五三年第三册，六六四至六六五页）。
5The first proof of knowing the Body is that we cannot be individualistic… Before one knows the Body, he is an individualist and can be individualistic. His life, his actions, his work, and his service are all individualistic. Outwardly, he appears to be one with the brothers, but there is no real coordination or knitting together. Not until he grows deeper in life and knows the Body to a certain extent does he see that being a Christian is a corporate matter and that he cannot go on without fellowship in the Body, nor can he depart from the coordination of the members. The Body of Christ becomes a practical matter to him. In the church life he can no longer serve alone. In the innermost part of his being, he feels that he needs to be a Christian together with others… He cannot work without the coordination of the brothers and sisters, and he cannot live without the support of the church. It is at this stage that he is being knit together spontaneously with all the saints to become one Body, no more to be separated. All those, therefore, who can still be individualistic do not know the Body, and all those with a true knowledge of the Body definitely cannot be individualistic.
