There are three things that spread the Christ life to us: baptism, belief, and that mysterious action which different Christians call by different names—Holy Communion, the Mass, the Lord’s Supper.
If you have once accepted Christianity, then some of its main doctrines shall be deliberately held before your mind for some time every day. That is why daily prayers and religious reading and churchgoing are necessary parts of the Christian life. We have to be continually reminded of what we believe. Neither this belief nor any other will automatically remain alive in the mind. It must be fed.
C.S. Lewis, Mere Christianity
Here is one area where I depart from Lewis’ beliefs; religious practice is an outgrowth of walking in Christ’s way, not the means. In Lewis’ day, the two may have seemed one and the same, but they are not. The only thing that truly spreads Christ’s life to us is faith, producing in our lives the fruit of His Spirit. To pursue the religious practices he listed as a primary goal is simply to hang religious window dressing on a carnal life. Really, Uncle Jack. I thought you knew better.
