As a Catholic, and once an agnostic, the more I study Catholic Theology, the more obvious it becomes how “perfect” the philosophy of the Church is—being universal and giving dignity and worth to everyone. No other faith is equivalent or as well-reasoned—only some Christian ones came close, but without a centralized head and the magisterium, they became whatever pop culture wanted them to be and many became meaningless, and the Bible became just an “evolving” changeable standard—a joke, which becomes useless as a guide for morality.
You are always a Catholic once you are baptized a Catholic!
