Christianity doesn't have dietary laws or dress codes, either. Those are easy, legalistic fillers that may let a person evade the complete reformation of your heart, mind, body, and soul that is true Christianity.
So when God Himself gave dietary laws and dress codes in His Torah, He was giving His people something weak and wicked?
God gave us rituals and cultural commandments not as a replacement for inner transformation, but as stepping stones for the young and spiritually immature and as a way to bring body, soul, and spirit together. This is why even Christians recognize the New Covenant sacraments of Baptism and Communion to be graces rather than "legalistic fillers," and why most Christians around the world have developed their own traditions and rituals--catechisms, confirmations, hymns, creeds, confessions, and ceremonies.
Now, I agree that any of these can become a substitute for a true, living, and transforming faith/faithfulness. On the other hand, so can "feel-good faith." The solution is not to avoid them like the plague, but rather to see them as what they are: tools, a means to an end, the end being the true and living Messiah (Rom. 10:4).
