The holy are entering already into the Coming Age and the Kingdom of Heaven, and through Christ's body, the Church, we may mystically interact with them.
May I ask if you have scripture to back up this statement?
First off, please stop saying "Scripture" as if it is a singularity. There are only "Scriptures" (plural).
Second, I have a few examples. St. John mystically entered into the Age to Come in the Book of Revelation. That's what the entire book is about. In that book: "When the Lamb broke the fifth seal, I saw underneath the altar the souls of those who had been slain because of the word of God, and because of the testimony which they had maintained; and they cried out with a loud voice, saying, 'How long, O Lord, holy and true, will You refrain from judging and avenging our blood on those who dwell on the earth?”
Which adds weight to the words of the Apostle:
"For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ."
"Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you."
"Amen I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom."
"...the Word of God, that is, the mystery which has been hidden from the past ages and generations, but has now been manifested to His saints"
"And he was saying, 'Jesus, remember me when You come in Your kingdom!' And He said to him, 'Amen I say to you, today you shall be with Me in Paradise."
"Most certainly I tell you, this generation will not pass away until all things are accomplished." and "Therefore when Jesus had received the vinegar, He said, 'Teteleste
[it is accomplished]!' And He bowed His head and gave up His spirit."
Another from the Apostle:
"These things happened to them as examples and were written down as warnings for us, on whom the fulfillment of the ages has come."
And "But being full of the Holy Spirit, he gazed intently into heaven and saw the glory of God, and Jesus standing at the right hand of God; he said, 'Behold, I see the heavens opened up and the Son of Man standing at the right hand of God.”
Finally, and most importantly:
"'Ye search the Scriptures, because ye think in them to have life eternal, and these are they that are testifying concerning me."
Before replying, remember that there is no Scriptural reading without a hermeneutical interpretation. Nobody interprets the Scriptures without a hermeneutic, whether they realize it or not. So you cannot say, "your reading is not the plain reading", because there is no plain reading, as there is no reading without a hermeneutic. Rather, you must set your hermeneutic against another hermeneutic, and make an apology for it.
