(Please read the passage cited above first.)
My sisters and brothers,
What do we read in the first letter of St John? We read that we should not sin, “but if we do sin we have an advocate with the Father, Jesus Christ the just one.
Jesus Christ is always living and is seated at the right hand of the father to intercede for us. Yes, he died, offering himself as a victim to expiate our sins and those of the whole world.
Our advocate is all powerful and ever-living. He is not going to die again. Nothing has more power than Christ. He has the power to save all sinners. No one can escape his power. Jesus Christ, our advocate, has the power to save us and everyone else and his advocacy always works.
There is no other advocate except the Holy Spirit. Can the Virgin Mary be our advocate and intercede or pray for us? Can the other saints intercede or pray for us? Can we intercede or pray for others? Yes, we all can because we are all joined to Christ and one with him because we are members of his body and so we share in his task of being advocate and interceding for others because of our union with Christ the advocate. One the other hand, without Christ, we can do nothing.
There is only one Christ, not more than one. The Christ who is in the glory of the Father is the same Christ who is present in his Church and the same Christ who does the sacraments. This Christ likewise is in each member of his body. There is only one Christ. The Christ who intercedes for us and the rest of the world as our advocate, is the same Christ who died and rose from the dead. He is the same Christ who is the only Son of the Father. This is the Christ who is one with all the members of his Church.
The Virgin Mary, all the other saints, the angels, all who believe in Christ and all who honor him, are members of Christ. Therefore, all of us are in union with Christ whenever Christ intercedes for the women and men of the world. We therefore end our prayers, “through Christ our Lord.” We ought to do everything we do in the name of Jesus because we are one with his body.
If someone sins, we have in Christ our advocate with the Father. Christ in his people, in his Church, in his sacraments, in his glory with the Father is always living to intercede for us before the Father.
