This is a passage misconstrued frequently to defend anti-catholic ideas, such as the saints and Mary being “mediators” for us. Firstly, the saints and mary are not referred to as mediators, but rather as intercessors. The definition of a mediator is someone who is "acting through" while intercession is “acting on behalf of someone.” God is acting THROUGH Jesus on our behalf, while the saints and Mary are simply ASKING on our behalf, which is exactly what happens when we ask our parents or friends to pray for us. We are not asking them to be mediators between us and God.
