If there was ever anyone who heard the word of God and kept it it was Mary.
How do you know? Precious little about what she did is even recorded in Scripture.
There were many throughout scripture that were faithful to God. The Catholic church has chosen Mary partly because they could incorporate the pagan “queen of heaven” belief to attract pagans into the church. If the myth the RCC perpetuates about Mary being assumed into heaven why isn’t there any record of it like there is of Elijah?
Anyone who truly wants to follow Christ needs to leave the bonds of the RCC and it’s pagan ways.
