Feast of Seven Sorrows of the BVM

The Catholic Church celebrates the Feast of the Seven Sorrows of the Blessed Virgin Mary today. Jesus gave Mary to be our mother when he was crucified on the cross (John 19:27). Not only does she take care of her adopted children, she is also set up as a model for us to imitate. She cooperated with God to bring Jesus to this world. Therefore, she is a prototype for all Christians who are supposed to bring Christ to this world too. She followed Jesus closely in the background in his public ministry, never ever overshadowed her son. She suffered together with Jesus during his crucifixion. Standing below the cross, the Blessed Virgin went through her martyrdom, bearing witness to the truth. Of course, we are not saved through her sufferings, but meditations on her sufferings would bring us closer to our Saviour.
The Church meditates on the following seven occasions of her sorrow.

1. when Simeon prophesized about the future of Jesus;
2. when they fled to Egypt;
3. when they lost Jesus for three days at Jerusalem;
4. when she met Jesus while he was carrying his cross to Calvary;
5. when she as standing at the foot of the Cross;
6. when Jesus was taken down from the Cross, the Pieta
7. when Jesus was buried.

When we think of the Beatitudes Jesus preached in Matthew 5, the image of the Blessed Virgin immediately springs to mind. She is poor in spirit (humble); she mourns; she is gentle and meek, she longs for the vindication of Jesus' cause, she forgives those who torture her son; she is pure in heart, she cooperates with God to bring peace to this world and she stands under the cross to suffer together with Jesus. If anyone can be called blessed, for sure it would be her.
We read Hebrews 5:7-9 in the celebration today. Here is an interesting verse trying to figure out why Jesus save the world in this funny way.
Although he was a Son, he learned obedience through what he suffered;
and being made perfect he became the source of eternal salvation to all who obey him (Hebrews 5:8-9).
Jesus suffered to learn obedience. His sufferings made him perfect. After suffering his death, he became the source of eternal salvation to all who obey him. The logic is puzzling.
First of all, the concept is alien to me: to learn obedience through suffering. What does that mean? How do people learn obedience? Through punishment! If a child does not obey, it receives punishment. After punishment, it learns a lesson. In order to escape punishment and thus suffering, you had better obey! In the case of Jesus, it is the opposite. He suffered because he obeyed! Had Jesus not obeyed the will of the Father, he would not have suffered on the cross.
Secondly, why does Jesus only become the source of salvation for those who obey him? Why is there such a condition? What about those who don't obey him? Shouldn't Jesus be powerful enough to be the source of salvation for all, whether you obey or not? The condition is also funny. Didn't Paul talk about justification through faith? Shouldn't the verse read: Jesus became the source of salvation to those who believe in him?
The theology in Hebrews is interesting. But I am afraid it is incomplete. It seems that the author of Hebrews did not understand that Jesus is God. The verses quoted above do not touch on the divinity of Jesus. In his divinity, there is no need for Jesus to be made perfect because he is already perfect and holy. For eternity, Jesus is the source of salvation. There is no need for him to go through the Passion in order to become the source of salvation. For me, the wording of Hebrews is puzzling because I have not studied theology. Probably some of you may be able to enlighten me on this point.

My dear Lady, pray for your adopted children. May the meditation on your sorrows benefit us and bring us closer to our Sweet Jesus. Amen.
