As a sojourner here on earth, we all need to keep in mind that one and only one faith is fully right. This faith was established by God, the Second Person of the Blessed Trinity while He was on earth. The God-Man established one and only one Church which He said will be led to all truth, and so is the very pillar and foundation of the truth. No other ecclesial community or faith system has that mission, promise and protection.
Man is indeed able to see things in natural moral law that do not require specific revelation. So, there are some truths taught in other faith systems. None of them, however, is able to teach the fullness of truth, and so many in those incomplete faith systems will go astray with the little truth they do have, which is not supported in the whole by a context of teachings without error.
It may be interesting to see how outside of God’s Church. man has arrived at some degree of understanding of natural moral law, and yet fails to see and integrate it fully into God’s plan.
Catholicism is the entire package established by God who is Head of His Catholic Church and no other. So, there is really no need for any other. At least God didn’t think so, and so I follow Him.
