If God is the God of the living and not the dead(He is), then why not ask for help from Paul? or one of the other saints? Actually the Word says we are all saints(in Christ). Should I ask for help from Martin Luther? Or Dietrich Bonhoeffer?
Where does it end?
There really is only one mediator and that is Jesus the Messiah, the Son of God.
I’m not anti-Mary, but she really can’t help us by us praying to her. Definitely an inspiration,though.
Only God can answer prayer.
Which is what the Church teaches. However, you apparently don't know the difference between a mediator and an intercessor.
“then why not ask for help from Paul? or one of the other saints?”
We can and do. It’s no different then asking Mary to pray for us, as to ask Paul to pray for us.
It doesn’t have to end anywhere. I’m not sure why you think this is a reductio ad absurdum, because that’s precisely what the Communion of Saints teaches, that all the Saints are in heaven and we can ask them to pray for us.
“There really is only one mediator and that is Jesus the Messiah, the Son of God.”
This is true. However, we are called to pray for one another. This is no different for the Saints in heaven as it is for those of us still here on earth.
“I’m not anti-Mary, but she really can’t help us by us praying to her. Definitely an inspiration,though.”
We aren’t praying to her. We ask her to pray for us.
