And then they made up the story of Mary being bodily assumed. The Catholic Church is a cult for sure.
If it comforts you to think that the story is “made up” then there is nothing I can give you to open your heart to the truth.
What you and other protestants don’t seem to understand regarding the doctrines of Mary is that these doctrines are not revelations about Mary, nor are they NEW revelations about God.
They are a deeper understanding of God’s love for us, His creatures who are now His children, adopted through Jesus.
God meant for us to be sinless and blameless and to live with Him in paradise. It was for this that He created us. He wants us all to be perfectly united to Him so that we may share in His glorious presence in heaven.
There is no human who was more perfectly united to God than Mary, who carried Him in her womb. Her unity which is unique and different from that of Jesus who WAS God.
In Mary is the fulfillment of all the love of God for us and the fruition of the redemption that is ours through Jesus.
