“Believing in Christ means the acknowledgment that one belongs not to one’s self but to him, and belonging to him means belonging to the body of Christ, the community of brethren who have been redeemed and claimed by the one Lord. This belonging to Christ and hence to one another is the presupposition and crucial preorientation of all the believer’s choosing and doing. The believer is not on his own in matters of conduct, nor is he, on the other hand, in possession of prescribed requirements for life in Christ. What is to be done must be discerned and decided in the individual case but always with reference to God’s gift of love as it has been met in Christ and God’s demand of love as it is repeatedly met in the neighbor.”
