What about the 72.5% that's missing from the mass readings in the Catholic Church?
Diversion aside, the fact remains unchallenged.
The title of the article is either a deliberate lie or the author of the article is ignorant of Scripture and the Truth of Jesus Christ our Lord.
Obviously, what someone does or doesn't read aloud in Church isn't anything like someone insulting the Holy Spirit by claiming they know more about what should be accepted as Scripture than the Holy Spirit does and then throwing a portion of His Word into the trashcan.
Unlike the joke about what percentage of Scripture is read aloud, it's an absolute fact, not a joke, that a major portion of the same Scripture Jesus Christ Himself quoted and preached as the Inspired Word of God is not accepted by non-Catholics.
People who do not accept His Word in full reject portions of Scripture either because they are ignorant or because they know His Word totally refutes the false doctrine of Sola Yourselfa and other convenient doctrines cherished by convenient spirits. Quite a few such folks then even go on to make fools of themselves by saying that Catholics accept false doctrines.
The Truth is that Catholicism is built solidly on the Inspired The Word of God, all of it.
People who preferred following Eve to following Jesus Christ threw portions of the Word of God into the trashcan, others since then have been misled and don't know the Truth, and still others know they're ignoring His Word but pretend, like the Pharisees, that what someone threw out doesn't exist. None of that changes or eliminates the Inspired Word of God Catholic Doctrine and teaching is based on.
Claiming to accept His Word only after throwing out part of His Word is a dangerous path to follow. Jesus Christ said to follow Him, not to follow what fits into the latest Sola Yourselfa fad or emerging fad.
