We begin the Part 3 by looking at mediation Paul writes to Timothy that there is one Mediator Jesus and Vatican II furthers this idea by saying that Mary devotion to Mary shows the power of the mediation of Jesus. The motherhood of Mary is where her mediation lies and Mary show us the end all be all to mediation based on her complete willingness to become the handmaid of the Lord. Jesus points to this at the Crucifixion when he gives Mary to the beloved disciple “Son behold your mother, Mother behold your son” This is Jesus giving Mary the universal role of Mediator we are all her children. John Paul II goes on noting that Mary is a permanent model for the Church. Then we have the Popes hopes for the Marian Year (1987)
In the Conclusion John Paul looks at the end of the Divine Office (liturgy of the hours) and the invocation to Mary. “Loving Mother of the Redeemer, gate of heaven, star of the sea,
assist your people who have fallen yet strive to rise again. To the wonderment of nature you bore your Creator!” This is a great summary of the whole role of Mary, she is the one individual that we all turn to as she is our mother. We might fall but Mary is always there to help us back up, this is not only as individuals but as the Church herself. As Pope Benedict would say several years later “It is necessary to go back to Mary if we want to return to that ‘truth about Jesus Christ’, ‘truth about the Church’ and ‘truth about man.'”This is why Mary should be more important in all Christian lives for in Mary we can find a model to follow.
