It is more than an accident that both Judaism and Christianity should begin with a great act of deliverance; that that act of deliverance should constitute a community, and that a memorial rite should be the center of the ritual of both. The Lord's Supper historically took the place of the Passover. It was instituted at the Passover and instead of it. It is precisely the same in design, a memorial feast appointed to keep up the vivid remembrance of the historical fact to which redemption is traced; and not only to keep up its remembrance, but to proclaim the importance of extending that remembrance through all life.
Notice the peculiarity of both the Jewish and the Christian rite, that the center point of both is a historical fact, a redeeming act. Judaism and Christianity are the only religions in regard to which this is true to anything like the same extent or in the same way. Christianity as a revelation is not so much the utterance in words of great religious thoughts as the history of a life and a death, a fact wrought upon the earth, which is at once the means of revelation and the means of redemption. This is a feature unshared by other religions.
This characteristic determines the principal object of our religious thought. The true object for religious thought is Christ, and His life and death.
All religious truth flows from and is wrapped up in that: e.g. theology, or the nature of God; anthropology, or the nature of man; soteriology, morality, etc. All truth for the individual and for the race has its source in God's great redeeming act. Religious emotion is best fed at this source, e.g. thankfulness, wonder, love: all these transcendent feelings which are melted together in adoration. Here is where they are kindled. You cannot pump them up, or bring them into existence by willing, or scourge yourself into them, any more than you can make a seed grow by pulling at the germ with a pair of pincers, but this gives the warmth and moisture which make it germinate.
The clear perception of this truth is valuable, as correcting false tendencies in religion, e.g. the tendency to be much occupied with the derived truths, and to think of them almost to the exclusion of the great fact from which they come; the tendency to substitute melancholy self-inspection for objective facts; the tendency to run out into mere feeling.
The command requires of us a habitual occupation of mind with the great deliverance.
And the habitual presence of this thought will be best secured by specific times of occupation with it. Let every Christian practice the habit of meditation, which in an age of so many books, newspapers, and the distractions of our busy modern life, is apt to become obsolete.
