It is a common belief today that "loving" someone simply means affirming their personal decisions no matter how destructive their actions or beliefs are. This is lie from the father of lies. God's law defines what is loving. To love God and neighbor, you must observe the law of God.
"Every service is a structure of acts and words through which we receive a sacrament, or repent, or supplicate, or adore. And it enables us to do these things best — if you like, it “works” best—when, through long familiarity, we don’t have to think about it. As long as you notice, and have to count, the steps, you are not yet dancing but only learning to dance. A good shoe is a shoe you don’t notice. Good reading becomes possible when you need not consciously think about eyes, or light, or print, or spelling. The perfect church service would be one we were almost unaware of; our attention would have been on God."
