Of course, the miracles are a result of the intercession to Christ by the saints. They are much closer to Him than we are.
BTW, did you ever ask anyone to pray for you? Same thing. We ask the saints to pray for us.
No displacing Christ at all. Are you really voicing misconceptions that you were taught along the way?
If I can get JESUS CHRIST to advocate on my behalf, why on Heaven or earth would I waste my time with some dead saint?
