Each to his own, I guess.
I find the "ritualism" of the Catholic Church far from empty. On the contrary, it is historically, symbolically and spiritually rich. These are the sacred mysteries. The mysteries handed down from time immemorial. The mysteries in which the saints and fathers of the Church partook and which make Christ truly present. There is an incredible source of grace, strength and holiness contained in these rituals.
On the other hand, what I find empty is some guy in a suit giving me his take on a passage of Scripture or the superficial rock concert atmosphere which can be found in some church auditoria.
For me, religion is not about getting a "buzz" or the constant search for some new "experience". It's about an interior spiritual life lived in union with the crucified Christ.
Only fully trusting the Atonement of Christ to have paid the full and total debt for your sin will.
