At a glance:
The Bible teaches that there is only one intercessor. Or does it? Can we not intercede for each other and cannot our dead relatives and dead saints intercede for us? We living people, intercede for each other in the name of Jesus, which makes Him the intercessor. We are not to communicate with the dead and so if they are interceding for us we appreciate it (although the Bible does not tell us) but we are not to pray to the dead, but to God only.
