I don't think you quite grasped Fr. Pope's point.
Of course we believe He is already with us. Charles Pope just says that in every paragraph he wrote.
But Christ has special ways of dwelling in special places.
Otherwise, even "where two or three are gathered" or "within the hearts of we who believe in Christ" or "on Sinai's height, enveloped in a cloud glory" wouldn't be any more special than anywhere else.
It's like this: you are with your spouse when you are asleep on the sofa, and your spouse is sitting in an armchair right beside: the two of you are present. You're even "more present" if you're both on the sofa. And even "more present" if you're both on the sofa and awake. And "more present" yet if you're on the sofa, awake and entwined.
All present: but different intensities of presence.
I'm not sure the Msgr has grasped the Gospel's point.
Of course we believe He is already with us.
It doesn't sound like it!
When the Scriptures tell us He's dwelling in us....not sure how much more present or intense you can get than that.
By this we know that we abide in Him and He in us, because He has given us of His Spirit. 1 John 4:13 NASB
9However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him.
10If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness.
11But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you. Romans 8:9-11 NASB
