I can try and help, I suppose.
Intercession of the saints is a Christian doctrine held by Eastern Orthodox, Oriental Orthodox, Roman Catholic, and some Anglican churches, that deceased saints and the Blessed Virgin Mary intercede (or pray) for believers, and that it is possible to ask deceased saints for their prayers. The doctrine of requesting intercession from deceased saints can be found in Christian writings from the 3rd century AD. Saints are called on in prayer due to their proximity to God, because of their holiness, and their accessibility to humans. For the Late Antique, medieval, and much of the Early Modern periods, the practice reflected the common view of the “court of Heaven” as being in some ways similar to earthly courts. The faithful often preferred to make a request through a saint rather than directly to God, just as an earthly request to the monarch was often best handled by using a patron with standing in the court as an intermediary.
You know, God IS a King. Are we so arrogant as to consider ourselves equals to God? I don’t think so.
This is the Roman Catholic View:
Roman Catholic Church doctrine supports intercessory prayer to saints. Intercessory prayer to saints also plays an important role in the Eastern Orthodox and Oriental Orthodox churches. Also some Anglo-Catholics believe in saintly intercession. They may point to such Scriptural passages as Tobit 13:12-15, Revelation 5:8, or Revelation 8:3-4, which depict heavenly beings offering the prayers of mortals before God, and in addition to James 5:16 (where all those in heaven can be presumed to be living righteously), which states the prayer of the righteous is powerful and effective. Both those for and against the intercession of saints quote Job 5:1.
Intercessory prayer to saintly persons who have not yet been canonized is also practiced, and evidence of miracles produced as a result of such prayer is very commonly produced during the formal process of canonization.
If even the Orthodox and Oriental churches agree with the doctrine, could 1.7 billion Christians in the world be wrong? (It is a fact there are more Christians in the world than there are Muslims, Hindus and Buddhists)
This is the Protestant view:
Many Protestant churches strongly reject all saintly intercession, in accordance with verses like 1 Timothy 2:1-5, which says that Jesus is the sole mediator between God and man. They also point to the fact that there are no examples in the Bible of living humans praying to dead humans — Jesus Christ being the lone exception, because He is believed to be alive and resurrected, and because He is believed to be both human and Divine.
The issue with this is that when it says “the sole mediator”, it really means we can only go to Heaven THROUGH him, it does not reject communication with God through a saint, who happens to be close to God, like a subject is to his or her King. We’re knight’s and ladies of Heaven. Can’t forget that.
But just as there are knights, so are there peasants, dukes, earls, marquises, barons, counts, etc. No one is above the King.
