‘His Church’ is not the Catholic Org. His Church is like speaking of the student body, of a particular school, and that Body of Christ, His Church, is made of ALL those who have done as God commands, they have believed in Whom God sent for their deliverance. That Church Jesus is coming for soon, so that we of His Body meet Him in the air. The Catholic Org isn’t going anywhere when the Rapture Departure happens. The Catholic Org may have to watch CNN to find out the Departure has occurred.
That is just your fallible personal opinion.
It is not God’s Truth. Nor is it the historical truth.
You may be lucky to live to see God’s warning when he promises to show us our souls.
