Mediator and intercessor are linked. they can be used interchangeably can they not? do they not mean the same?

Jesus is the only mediator between God and man. No one else—not Mary, not any previous Christian saints, not angels—has the power to intercede for us before the throne of the Almighty. Christ alone mediates and intercedes between God and man. “For there is one God, and one mediator also between God and men, the man Christ Jesus” (1 Timothy 2:5).

Romans 8:34 says that it is Jesus who intercedes on behalf of us. Speaking of Jesus, the writer to the Hebrews says, “Therefore He is able also to save forever those who draw near to God through Him, since He always lives to make intercession for them” (Hebrews 7:25).

Jesus is the Advocate for Christians, meaning He is our great Defender. This is the intercessory role He currently fulfills for those who are His (1 John 2:1). Jesus is always pleading our case before the Father, like a defense lawyer on our behalf.

Jesus is both mediator and intercessor. Mary, who is dead, is not.

You're what I point at when I'm warning people about the dangers of religion on the simple mind.

no their not the same. the Mediator judges between two parties to work out differences. a intercessor intercedes for a individual in their favor.
