Do Catholics Worship Mary?

Just as Jesus honors His mother, so do we, for on the cross Jesus gave His mother to all mankind when he said to St. John: …Behold thy mother! (Jn. 19:27)

You can only be saved through Jesus Christ. Mary's only mission is to lead us to Christ. At the wedding of Cana, when the wine ran out, Jesus listened to his Mother's plea on behalf of the bride and groom and turned water into wine. (Jn. 2:3-7).
No one knows or loves her son more than Mary. We ask Mary to pray for us (mediate) or anyone else in need in the same manner we ask a friend to pray (mediate) for us. We believe that Mary continues to intercede for us to her son. It is for this reason we ask Mary, in faith, for her prayers. Our prayers to Mary are an addition to our prayers to God--not a replacement.
Mary is not only the mother of Catholics but of all God's children.
In Revelation 12:1-17 it clearly shows Mary as the mother of all. Verses 1-2 speak of a woman who was with child. This woman was not an ordinary woman as the verse indicates: And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars: And she being with child cried, travailing in birth, and pained to be delivered.
Some say that this verse is symbolic of the church. But who is the child (Clue: Jesus)? What woman can you think of, in the Bible was with child and was traveling? (Clue: Mary).

Then verse 5 goes on to say that she brought forth a man child who was to rule all the nations with a rod of iron. Wonder who that could be? (Clue: Jesus).

In verse 9 the "old serpent" is identified as Satan.
In verse 17, we see that the dragon (Satan) was angry with the woman (Mary) and went to make war with the remnant of her seed (mankind), which keep the commandments of God, and have the testimony of Jesus Christ.
Conclusion: Mary is your mother!
