Sure does sound like John is saying we each have the Holy Spirit to help us. Didn't see it limited to just a "church".
John 14:16
I will ask the Father, and He will give you another Helper, that He may be with you forever; 17that is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him, but you know Him because He abides with you and will be in you.
John 15:26
When the Helper comes, whom I will send to you from the Father, that is the Spirit of truth who proceeds from the Father, He will testify about Me, 27and you will testify also, because you have been with Me from the beginning.
Ephesians 1:13-14
13In Him, you also, after listening to the message of truth, the gospel of your salvationhaving also believed, you were sealed in Him with the Holy Spirit of promise, 14who is given as a pledge of our inheritance, with a view to the redemption of Gods own possession, to the praise of His glory.
And reading just this board and catholic comments shows how incorrect your statement is! LOL!!!
The indwelling of the Holy Spirit was given to individuals. It was NEVER given to a group or organization.
