I’m pulling out the pertinent paragraph.
***Because he is the only God-man and the Mediator of the New Covenant, Jesus is the only mediator between man and God (1 Tim. 2:5), but this in no way means we cannot or should not ask our fellow Christians to pray with us and for us (1 Tim. 2:1–4). In particular, we should ask the intercession of those Christians in heaven, who have already had their sanctification completed, for “[t]he prayer of a righteous man has great power in its effects” (Jas. 5:16).
As the following passages show, the early Church Fathers not only clearly recognized the biblical teaching that those in heaven can and do intercede for us, but they also applied this teaching in their own daily prayer life.
The Saints certainly DO qualify as righteous, I seriously doubt that her auntie meant we should circumvent Christ.
