There appears to be quite a tradition of miracles in the Catholic Church.
Thankfully most of them appear to lack the showy questionable spectator sport quality of the Charismatic 'faith healers' that are high in the councils of American Evangelical Protestantism.
But...
I believe that if God meant for me to be spontaneously miraculously healed of my impairments, He'd have done so by now...I believe that God thinks I'm fine just as I am. That Me-With-Impairment exists for a reason that is at present unknown.
I don't think I need that sort of healing, don't request it, and will try to find a thousand graceful ways to decline the process if approached by fellow parishioners.
I *do* need spiritual, emotional and mental 'healing' on a number of fronts, and will pursue those through both the mechanism of the Church and present medical intervention.
If people believe they need a miracle so much that they make a pilgrimage to Lourdes, or elswhere, and their journey is rewarded...that's cool and amazing to me...but doesn't make me envy the healed. They are healed for a reason. I am not healed for a reason. It's all the same to me.
