When repeated often, doesn't the Lord's Supper run the risk of becoming mundane and lose its meaning? Why did Jesus command its repetition?
For the same reason remembering God's laws becomes mundane and loses its meaning ... (sarcasm)
That is why God directed in Deuteronomy 6:4-9:
4 Hear, O Israel: The LORD our God, the LORD is one. F15 5 Love the LORD your God with all your heart and with all your soul and with all your strength. 6 These commandments that I give you today are to be upon your hearts. 7 Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up. 8 Tie them as symbols on your hands and bind them on your foreheads. 9 Write them on the doorframes of your houses and on your gates.
We are in the process of training a new puppy right now, all the books say that the dog that is under four months of age has a memory/attention span of about 3 seconds. An act and reward or an act and a punishment separated by more than 5 seconds will not necessarilly be associated in the puppy brain.
Humans, especially as a community whole are a little better. Even though my local congregation only celebrates the Lord's supper on a weekly basis as was the custom in Acts - this is one point where I can not even complain when congregations offer this partaking even on a daily basis - like in the Roman Catholic churches. My complaints come when they shed it of its core meaning.
As the study stated near the end: I think it is ironic, that some churches relegate the Lord's Supper to an only occasional observance, when the sacrament contains the church's central message.
Amen brother - keep up the great teaching!
