For example, here is part of a very comforting passage from an encyclical by Pope Leo XIII:
Thus as no man goeth to the Father but by the Son, so no man goeth to Christ but by His Mother.
I wonder what Pope Leo XIII meant when he said the bolded portion of your post, as it has no basis in scripture.
Jesus said, He who comes to me I will not cast out. He didn’t say, He who would come to me must first go through my mother.
Scripture also says, he who calls upon the name of the Lord will be saved. Not, he who calls upon the name of the Lord through Mary will be saved.
The Book of Hebrews is about Jesus becoming our High Priest through whom we have direct access to God. We do not need to go through some other hierarchy such as first to Mary, who will then lead us to Jesus our High Priest, who then leads us to God.
If Mary was our way to Jesus, surely this would have been a scriptural teaching, but even Peter, in speaking to women, says that women are daughters of Sarah (Abraham’s wife) if they do what is good. (I Peter 3:6). So if Mary was high and exalted at that time and our only way to reach Jesus and obtain salvation, Peter, our First Pope seemed not to have known about it.
Surely a doctrine as important as the salvation of our souls would be correct as stated in our guidebook the Holy Bible. And God has not changed this. Even Mary herself, in all the approved apparitions, basically had the same message: “Turn to My Son and pray, pray, pray.” I wonder what Mary would say to this teaching that no one could reach her son except they went through her?
