“One friend made the practical point that if no one ever prayed for the help of non-canonized saints, there would be no such thing as a saint recognized by the church. It takes miracles, obtained through the prayers of the faithful, for a holy person to be recognized as a saint by the church.”
This article actually speaks to a far deeper question than it may seem. What of people we knew ourselves who seemed servants of God? Could we ask for a family member who has died to pray for us? Someone we knew in our parish? Perhaps even the priest? An old friend who died? Besides someone we just heard about, in one way or another.
