Yes—
“When the Son of man cometh, shall He find, think you, faith on earth?”
This rhetorical question implies that faith will be scarce when Christ returns. That’s consistent with a remnant Church, persecuted or hidden, holding fast to the Deposit of Faith while the visible structures are occupied by a false church.
It’s not the first time God has worked through a faithful remnant:
Noah’s family
Elijah’s 7,000 who did not bow to Baal
The Apostles after Christ’s arrest
Catholics during Arianism
In every age of apostasy, God preserves a faithful few. We believe we are part of that remnant—not due to pride, but fidelity to what was always believed.
