I would like to help you on the intercession of saints. However it would take a very long reply. I would like to send you a CD that would answer your question but I guess that would not be possible. The next best thing would be to give you a link to go to.
The speaker is John Martinogni. The link is:
www.biblechristiansociety.com
When you get to the page click on the title "Apologetics-Free Audio Downloads.
When you get there scroll down to the title “Communion Of Saints.”
I second this advice - his talks are fantastic!
firstmode, the other thing I would add is regarding the Body of Christ which someone else covered -
1 Corinthians 12:20-21
As it is, there are many parts, but one body. The eye cannot say to the hand, “I don’t need you!” And the head cannot say to the feet, “I don’t need you!”
You see, there are many parts of the Body of Christ, those of us here on earth, those in purgatory, those in Heaven, the saints, the angels, the archangels, the Holy Trinity! We all need each other, this is the communion of saints.
We also know from
1 Corinthians 12:26 “If one part suffers, every part suffers with it; if one part is honored, every part rejoices with it.”
We also know from
Luke 15 that “there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent.” - so surely those in heaven are aware of what is happening here on earth don’t you think?
The final thing I will offer is **Hebrews 12:**1 “Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us.”
Who is the cloud of witnesses?
For Catholic belief, it is a great comfort for us in this wicked world to have all the angels and saints in Heaven praying for us to continue in perseverance. If we can ask other Christians on earth to pray for us, then there is no reason we can’t ask Christians in Heaven to pray for us too since we are all, through our baptism, members of the body of Christ - and the body of Christ is made up of many parts and cannot be separated or divided.
There is also a Catholic Answers radio talk that you should listen to as well - it’s from about a year ago but I still have it on my ipod as it explains things quite nicely

I hope this helps
