Can you explain the difference?
According to Vines Expository Dictionary of New Testament Words, a mediator is "one who mediates between two parties with a view to producing peace". It is in that sense that the Lord Jesus is the only mediator bwetween God and man (I Tim 2:5).
We have only one mediator but many intercessors. Mary and the saints are intercessors as are our fellow believers.
Technically intercession is a form of mediation. A mediator is a go-between. An intercessor is a mediator whose specific function is to plead someone’s case before a higher authority.
RE: We have only one mediator but many intercessors. Mary and the saints are intercessors as are our fellow believers.
So, do we pray to these intercessors?
I talk to LIVING intercessors who are here on earth. I don’t talk to ( much less pray to ) departed intercessors.
