The Holy Spirit works through the lives of the individual believers who ARE the church, the organism, the TRUE church, the body of Christ.
It's just not *the Church*, capital *C*, which by precedent refers to the Roman Catholic church, the organization.
In the letter to the Corinthians, Paul writes to the believers in Corinth....
1 Corinthians 12:27 Now you are the body of Christ and individually members of it.
“Now you are the body and individually members of it”
That being the case, and knowing that as a person who has given myself totally to Jesus Christ, I am a part of His Body.
Therein lies a problem with all the condescension of those Catholics who are part of His Body; as St. Paul wrote, He cannot deny us, for He cannot deny Himself.
Jesus also said that He would not cast out any who come to Him. I cannot be cast out for I have come to Him.
What is to be done with people like me? Say it isn’t true that I am “saved”? No—there is no way that can be said.
Neither can it be said by putting ALL Catholics together and making claim that they aren’t sons by adoption based on the personal opinion (belief) that assumes that their faith is in error.
