The writers of the New Testament were Jews who were living under the Law.
Until they were not. They were Jewish in background but became Catholics in belief and practice.
Paul, the most prolific among them, continued the Jewish custom of returning to Jerusalem for the feasts at the Temple, which is where he was arrested for the last time.
Eventually Catholics were ousted from the Temple. And? That doesnt stop them from being Catholics. Nor did stop them from being Jewish in background.
Christs catholic church rose from the ashes of the Temples destruction in 70AD,
No, Christs Catholic Church was born on the cross (portrayed in art as coming out of Christs side the blood and the water representing the sacraments of Baptism and Eucharist).

when the new heavens and new earth were ushered in.
No. The new heaven and new earth are at the end of time (2 Peter 3:10) thats why God says they will endure forever before Him in Isaiah 66:22.
However, by that time, the entire New Testament had been written, the last book of which was Revelation, written no later than 68AD.
What John saw in his vision of the new heaven and new earth had not yet happened (2 Peter 3:13).
Roman Catholics, calling their sect THE Catholic Church, mistakenly conflate the rise of their sect with the birth of the catholic church is undeniably and irrefutably false.
No, your comment right there is false. 1) We conflate nothing. We merely see what is. 2) We are not a sect. Only Protestants have sects.
One arose from the immediate end of Temple Judaism while the other appeared on the scene hundreds of years later.
False. The Catholic Church was born on the cross. No Christian sect of any lasting duration began over the collapse of the Temple. The Church already existed and was revealed to the world on Pentecost.
“The new heaven and new earth are at the end of time (2 Peter 3:10)”
Peter also wrote that “the end of all things was near.” (IPeter 4:7)
He wrote that to the Jewish diaspora living during his day. (IPeter 1:1), not to us. So do you reject Peter’s words, the man whom you view to be the first pope???
