Jesus said that the greatest commandment is to love God, with all your heart, with all your mind and with all your soul.  The liturgy is the organizing element that allows us to love God and receive the gifts of his sacraments, so that we can learn to love our neighbor in our daily lives.  But of course, if you believe in the primacy of conscience over Scripture (the word of God) and Tradition (accumulated wisdom) then you will naturally prefer to worship God in your own way and on your own terms.  But if that is the case, why would you even call yourself Catholic (universal)?
