I guess I don’t get the issue. Why shouldn’t Jesus appear on a Nintendo? He appeared as a human. After that could anything be more humiliating, unworthy, or inappropriate of the Son of God?
As to recognizing such an apparition or vision, as to Peter at Caesaria Philippi so also to us: to recognize the Lord is an operation of the Holy Spirit.
And if this event, whatever it is, leads this person to increased piety and devotion, then what’s the problem?
Just as no one is required to believe that this is meaningful so also no one is required to scoff. I certainly am not going to tell my Lord to whom and how he may appear.
Who said there was an issue? Who made it a requirement to react one way or another? Not I. Maybe Catholics should be posting these apparitions as "Devotional" threads, if they're so concerned about them being disrespected.
