Hello Jeanne1184. Glad to see you are back in the discussion as well.
We already agree that Peter’s trials were of benefit to us (and him), so I’m not quite sure why you spelled it out.
Because other people are reading this and may find benefit if an idea is expounded upon (When I come across someone who has done some “homework” here in an area that I am seeking to go deeper I am always appreciative . . . even if I don’t post public “Thank Yous” near enough).
ACTS 2:16-20 16 but this is what was spoken by the prophet Joel: 17 'And in the last days it shall be, God declares, that I will pour out my Spirit upon all flesh, and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams; 18 yea, and on my menservants and my maidservants in those days I will pour out my Spirit; and they shall prophesy. 19 And I will show wonders in the heaven above and signs on the earth beneath, blood, and fire, and vapor of smoke; 20 the sun shall be turned into darkness and the moon into blood, before the day of the Lord comes, the great and manifest day.
CCC 715 The prophetic texts that directly concern the sending of the Holy Spirit are oracles by which God speaks to the heart of his people in the language of the promise, with the accents of "love and fidelity."85 St. Peter will proclaim
their fulfillment on the morning of Pentecost.86 According to these promises,
at the “end time” the Lord’s Spirit will renew the hearts of men, engraving a new law in them. He will gather and reconcile the scattered and divided peoples; he will transform the first creation, and God will dwell there with men in peace.
Recall these ARE the “last days”. Ever since Jesus came into the world.
“The “last days” are not what “Rapturists” might think (OK count down only 60 days or whatever to the end of the world).
The “last days" refer to the New Convent era.
The pouring out of the Holy Spirit means a relationship with God in peace for all who desire such (whereas before Christ’s work, this would have not been possible).
The BEGINNING of the ordinary means for this is being “born again” or being “born of water and spirit” (Baptism). This relationship is right NOW but it is even fuller at the end of time (when EVERYBODY gets their bodies back whether they end up in Heaven or they choose and want to go to Eternal Condemnation).
There are LAYERS of meaning to Acts 2:16-20.
In one sense it refers to the “coming of the Lord” upon our spiritual (and in some cases ethnic) ancestors, the Jews. (“St. Peter will proclaim their fulfillment on
the morning of Pentecost” as per CCC 715 above).
The “coming of the Lord” means Covenant Judgment. You can do a word search in the Old Testament and see this for yourself.
This was all fulfilled at the destruction of the Temple (etc.). Even though these cosmic signs may be being referred to figuratively, Josephus even describes many of them as occurring explicitly before the destruction of the Old Covenant Temple!
In another layer (or in another sense) it refers to Covenant Judgment when WE die. This is a more microcosmic sense.
And Eschatologically, it refers to the End of the world (Covenant Judgment upon members of the Church–see CCC 675-677). ( . . . “
at the “end time” the Lord’s Spirit will renew the hearts of men. . .” again as per CCC 715 above)
These “layers of meaning” are laid out for us from the Church historically and yet again reaffirmed recently historically in the CCC (see CCC 115 through 119 to see how the Church expects us to know how “layers” of meaning in Scripture passages are present and can still be in a sense “mined for gold”).
The “living stones” concerns us all being built into the New Temple—Jesus Christ and His body (explicitly called “The Church” five different times within Scripture). You can look up the verses for yourself as I don’t want this post to get too long.
In one sense Jesus is the foundation. In another sense St. Peter is the foundation. In another sense the Apostles and prophets are the foundation. Then we as living stones get built into (incorporated into) the New Temple, Jesus Christ. And just to make sure you know it, the stone Temple building has NEVER been rebuilt.
The Church = The Body of Christ (in a corporate sense).
That’s WHY Jesus said “tear down this Temple and I will rebuild it in three days”.
Yes, Jesus was talking about His Resurrected body personally but in another sense, Jesus was talking about the Church too.
This all goes right back to the whole purpose of this thread (so I’m glad you asked) as this has to do with a real actual PHYSICAL Church on earth.
The Scriptures don’t define the Church as the “corpse of Christ” (which would be
a body with no soul), . . . .
. . . . nor does Scripture describe the Church as
only the “soul of Christ (which would suggest an
invisibility to His Church),
. . . . but rather the BODY of Christ (which has an invisible aspect and a united real PHYSICAL aspect too).
Dr. Scott Hahn discusses this concept in much more detail. He has a lot of stuff on YouTube and it is very good. He has even more audios at St. Joseph Communications. And he gives away many audios on his website
