However, you have it backwards.
If indeed you have trusted in the shed blood of the Lord Jesus Christ for your salvation and only in it, then you are our brother/sister in Christ through spiritual baptism (1Cor.12:13), even though you are a Roman Catholic.
A Roman Catholic is not a Christian, but there are Christians who are Roman Catholics and have not separated themselves from an apostate system.
Dear Brother/Sister
May God have mercy on your Soul! You are BLIND!
Perhaps I,ll address you later. I have a busy week ahead of me for now.
Peace in Jesus Christ
