There is no question about that. The reason to pray to saints in not to bypass the Mediator but to get to Him.
So you believe you need a mediator to get to the Mediator?
The short answer is yes. Saints are not of course mediators in the same sense Jesus is, because they did not redeem my sins. They are intercessors and teachers: they pray for me, and with me, and they advise me on decisions I need to make and they encourage me. They are a company of holy men that I love to keep.
