Membership in this church involves not only one's obligation to God, but also his obligation to his neighbor. To fulfill the demands of obedience to God as revealed through Christian Science, each one must acknowledge and obey no other Mind, no other Life, Truth, Love, than God, infinite good ; and this loyalty must also be demonstrated in association with mankind. In the Manual (p. 17) we are told that when the Church of Christ, Scientist, was first formed the purpose was "to organize a church designed to commemorate the word and works of our Master, which should reinstate primitive Christianity and its lost element of healing." Every member, therefore, understands that this design can only be carried out as each demonstrates the Christianity Jesus taught and lived, and proves it by his own works in healing sickness and sin. It is only thus that he can meet his obligations to God and his neighbor.
In The Christian Science Journal of August, 1889, Mrs. Eddy, in speaking of the observance of the sacrament, hints at the way in which this healing is to be apprehended, when she tells us of "solemn and silent self-examination by each member, as to his or her fitness to be called a follower of Christ, Truth; as to his real state of love toward man, and fellowship and communion with Christ; as to whether he is gaining in the understanding and demonstration of Truth and Love, coming out from the world and being separated from error; growing less selfish, more charitable and spiritual, yea, walking worthy his high calling." Could anything be more definite than this? Could a better correlative to Paul's advice to the early Christians be stated — the advice which he gave when he said, "But let a man examine himself, and so let him eat of that bread, and drink of that cup"?
No one understands so well as the Christian Scientist what it means to "eat of that bread, and drink of that cup." To partake of the bread of spiritual Truth which, while it feeds and sustains in a perfect way, at the same time demands that self-examination and self-renunciation which make it possible to cast out the false beliefs in a selfhood apart from God; this requires absolute consecration and devotion to Spirit. One must indeed hunger and thirst after righteousness with his whole heart, if he would continue to eat that which brings the purifying fires of the Holy Ghost.
