I’m no expert on the Eucharist. But I do know a thing or two about truth and right worship.
You can say that you love me. But what do you know about me? Can you love me if you don’t know anything about me? Only in an abstract, impersonal way, that is to say, “I love all people,” but you have no real personal love for me because you do not know me. (It is easier to love what we have seen, or what we know, than it is to love that which we have not seen. “if you cannot love your brother or sister who you have seen, how can you love God who you have not seen?”)
Then, I could be a legend made up for you. Everything you know about me is false. What, then, do you love? Your concept of me is not grounded in reality. Is your love for me truly for me? Or is it not, rather, for the false concept that you have of me? Does your love mean anything to me, I, knowing that you love a false concept of me and not my true self?
If you truly love me, you will search me out! You will wish to know who I am. And the more you know about me, the more you can love me. This reaches its highest potential in a husband and wife, who know one another and come into physical union with one another. Ideally, their love is nigh-perfected.
It is very important to worship the true God, and to know what He has made for us to know (like, for example, his presence in the Eucharist). It is also important to share in His literal, incarnate presence. What sort of father are you if you simply tell your son “I will keep you in my mind while you go to your baseball tournament!” Legitimate restrictions aside, get up and go there instead-- physically be a part of your child’s life if you love them. God so loved us that He is constantly among us.
To ignore Christ when he seeks to come down to us is so deeply sad that I can’t truly fathom it.
Do not forget that right worship is important to God. Why were Adam and Eve banished from Eden? Why was Cain’s sacrifice not good and Abel’s was? Why were Nadab and Abihu incinerated? Why was Uzzah struck dead? These all heard God’s Word and did not worship the truth, but instead worshiped their own idea of what was good. Most of them were probably good people… David was grieved for Uzzah, and Aaron for his sons. But it stands as a lasting testament to the importance of knowing God as Truth, not “whatever I think should be is good enough for God.”
I hope that in reflecting on this, you will see that in loving God as Truth and seeking to know Him as best we can, seeking to embrace Him as He comes to us in love on the altar, this is the answer to “what difference does it make?”
