My only concern is that there are many, many more Catholics that haven’t experienced this than those that have.
This is actually true of many, many Protestants as well . . .
It’s the ones that haven’t that I try to reach out to.
This is a point where it’s really illuminating to look into scripture, which is there to teach us about how we may be saved. Jesus said, “Whoever believes and is baptized will be saved.” Belief and baptism are repeatedly underlined as essential (1 Pet. 3:21; cf. Acts 2:38, 22:16, Rom. 6:3–4, Col. 2:11–12). Major supernatural experiences with God are never mentioned as essential.
Paul talked about the Gifts of the Spirit, as I’m positive you’re aware. These are what you’re talking about, and they are very valuable forms of intimacy between God and man. Incredible blessings

.
Paul also talked about the Fruits of the Spirit, and I think those are actually more important, because they are forms of goodness that overflow from a loving heart, and it is through love that we are united with Christ. Not through miracles and prophecies, according to Paul (1 Corinthians 3). He teaches that love is the “most excellent way.” In love, we are united with Christ (1 John 4:7). Miraculous powers or experiences don’t actually cut it on their own, according to Jesus:
On that day many will say to me, “Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?” And then will I declare to them, “I never knew you; depart from me, you workers of lawlessness.”
Knowing God experientially is extremely valuable, and I’ve been working to bring people into that experience all my life, ever since I met God myself that way. So I ENTIRELY am with you in wanting others to experience this. I’m just trying to frame this with a scriptural order of importance.
Of first and foremost importance for salvation, according to scripture, are belief and baptism. Love, according to John and Paul, is a crucial part of this, and from it the fruits of the Spirit spring. They are the emblem of a saintly life.
The Gifts of the Spirit are supernatural powers, often combined with other supernatural experiences, and they are one glorious way in which unity with Christ can manifest itself. They are secondary to the necessaries for salvation (belief and baptism) and love, in which every part of a life can become clothed with godliness. Love or lack of it can be a good indicator as to whether a person is following Christ truly or not. As Jesus said, once, “by their fruits, you shall know them.”
So I don’t think it’s scripturally appropriate to try to determine whether a person has a relationship with God or not, based on what supernatural experiences he or she may have had.
