I got your note and here are some things to help you minister to your mother. Be careful not to attach Catholicism or to belittle Mary. This will only put your mother on the offense. Just show her the verses and remind her the Bible is the Word of God and the Lord taught us not to follow man’s traditions – Mark 7:1-13 and Romans 3:4. Catholicism teaches that Mary herself was miraculously conceived and was therefore sinless and is now ascended as the queen of heaven. None of that is in the Bible. It is all the doctrine and tradition of men. It comes from paganism and is condemned in Jeremiah 7:18; 44:17-25… . There is no queen of heaven.
Now concerning Mary herself. Luke 1:28, she was blessed, to be chosen of God to bring His Son – The Lord Jesus Christ into this world. But God would have all eyes on HIM. Mary is “blessed” “among women” but note three things. First it is because “the Lord is with (her) thee.” Second she is blessed “among women” – she is not above all mankind, or sinless, but blessed among her kind, among other women. Third this was said also of Jael in the Old Testament – see Judges 5:24.
In Luke 1:27 Mary says: “And my spirit hath rejoiced in God my Saviour.” Only sinners need a Saviour. Mary was acknowledging her need of a Saviour and taking her place among all of mankind – Romans 3:10-12; 3:23.
Mary was a virgin “TILL” the Lord Jesus was born – Matthew 1:25. Then Joseph and Mary had at least 6 children together – see Matthew 13:55-57 where four of the Lord’s (half) brothers are named and his “sisters” (plural – meaning at least two) are mentioned.
Finally, note in the following references, how the Lord himself, spoke against exalting his mother, and He himself put her on equal ground with all his other followers – see: Matthew 12:46-50; and Luke 11:27,28; and John 2:1-5.
As Romans 3:24,25; 5:6-8; 6:23 says; It is through Jesus Christ and his payment for our sins in his death, burial and resurrection that saves. And by our faith in that, God saves us by his grace. Jesus Christ is the only mediator between a Holy God and sinful man through whom we can be saved – I Timothy 2:4-6. Prayerfully use these verses to teach your mother and give her the gospel.
