Is the Truth presented in Holy Scriptures incomplete? Are the Holy Scriptures "half a well" of Living Water?
People who don't even accept the entire Bible and each interpret what they do accept to suit their own preconceptions or glandular inclinations aren't going to get anything from Holy Scripture. The number of people who claim to be "Bible believing Christians" and teach that ordaining queers and/or marrying queers to one another is proof of that fact as is Scripture pointing out that the Word can fall on unsuitable soil.
It's been my experience that the majority of those in this country who claim to be non-Catholic Christians and these days even the majority of Catholic Christians are dedicated to Self and Self Alone to such an extent that for them Scripture is nothing but a book of sentences and phrases they can use like a giant box of Legos to build a "Christian" basis for anything they feel like doing or believing.
Scripture is an ocean of Living Water but people who start by only accepting a portion of it are inclined to seeing their Self as far more important than Scripture. In addition, having begun by agreeing that the Holy Spirit cannot and did not protect Holy Scripture from the inclusion of error they're unlikely to yield to the leadership of the same Holy Spirit they deny the power and perfection of while embracing personal interpretive infallibility.
I Corinthians 1:23 But we preach Christ crucified, unto the Jews indeed a stumblingblock, and unto the Gentiles foolishness :
I Corinthians 1:24 But unto them that are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.
