No, Jesus as our intercessor speaks on behalf of the saved against the accusations of the devil. He is the ONLY one who can do that. "For there is one God and there is ONE intercessor between God and man and that is Jesus Christ." It's in 1 Timothy.
ONE intercessor.
Praying for someone, such as "Harry" is not you and I coming before God and acting on their behalf as a savior against the devil's accusations. You and I have sin. We cannot do that. But we can and should and are told to pray for people. God listens.
We should lift people up in prayer. Jesus, the intercessor, can defeat the devil's lies and covers our sins with his blood so that they do not speak against us like the devil does.
Praying for people and being a holy intercessor who can abolish the devil's lies are two entirely things.
No Catholic alive believes that there is any intercessor before God for our sins except Jesus Christ. His death and resurrection is the focal point of our worship service.
Praying for someone, such as "Harry" is not you and I coming before God and acting on their behalf as a savior against the devil's accusations.
I never said that, but when you pray for someone else you are indeed acting as a mediator. You are thinking that the other guy's prayer is somehow going to help, so asking Joe from church or a saint in heaven, both of whom are alive in Christ is one and the same to me. So stop trying to nitpick between the two. Just go to God yourself and leave Joe out of it.
