They know that but keep denying it. What would they have left if all the pagan stuff was gotten rid of? I have been amazed at pictures posted on here because I had never seen them before. So, someone did a good job.
Actually not much. Even the Christian elements they have retained have been corrupted.
Just as protestants keep denying that they don't put themselves before Jesus and yet we see it time and again whenever they've concoted some new interpretation to Sacred Scripture to tickle some particular fancy of theirs. The whole, "That speaks to my heart" phenomenon and their entire scriptural interpretative bent is radically altered to coincide with their latest emotion.

We always have Jesus. First and foremost in the Eucharist. You would do well to remember that. We will have Jesus with us until the end of the world. But a protestant would never let that get int the way of a good anti-Catholic narrative.
