The Catholic Church is the true Church

Lutero said:

Yes, the true church has faithfully taught the gospel through the ages since it was received. The false RCC church has taught it's own perverted gospel and persecuted those who taught the true and refused to submit to the false.

The false Church is every variant of Protestantism. It is the Catholic Church which is the true Church of Jesus Christ:
Ephesians 3:10

King James Version (KJV)
¹⁰ To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,

Sincerely,

De Maria
