There are some who teach that the Virgin Mary is a co-redemptress, that she assists people in attaining salvation because she has special access to her Son. These are very well-meaning people, but the Bible differs with that view.
The Bible teaches, in the writings of the apostle Paul, that there is one mediator, or go-between, between God and man–the man Christ Jesus (see I Timothy 2:5). We do not need a mediator or buffer between Jesus and us. When Jesus was on earth, He was in a house teaching the people and ministering to them. There was such a large crowd outside that it was impossible for Mary and Jesus’ brothers to get in. Word was sent to Him, “Look, Your mother and Your brothers are standing outside, seeking to speak with You.” Jesus then pointed to His disciples and said, “Here are My mother and My brothers! For whoever does the will of My Father in heaven is My brother and sister and mother.” (Matthew 12:46-50). In this statement, He elevates all who love Him to the status of being in His “immediate family.” He was laying claim to a larger family than merely His earthly family, including His mother.
Mary is blessed among all women because she gave birth to our Lord Jesus (see Luke 1:42-45). But He has ascended and reigns over His church, together with the Father and the Holy Spirit. We are called upon to honor Mary, for the Scriptures teach that all generations will call her blessed. But there is nothing in the Bible to indicate that this wonderful woman has any special claim on Him or any role in our salvation.
