Majority Greek Text vs. Modern Versions
The New Testament is usually translated from original Greek. There are over 5000 ancient manuscripts surviving. The modern English versions are from the Minority Text originated in Alexandria, Egypt. Some so-called scholars are impressed because a couple of manuscripts are the oldest surviving complete New Testaments, surviving partially due to the dry climate in which they were preserved. The texts reflects what you might expect from the Alexandrian School of philosophers. It is identified with Origen, Westcott-Hort, and Aland., also called the Novum Testamentum Graece or Critical Text. Modernist liberals and unbelievers prefer it. It typically suppresses the deity of Christ and the ministry of the Holy Spirit, turning the Bible into a social gospel.
From Europe to the Near East, the Textus Receptus was derived from 95% of the Bible manuscripts that are referred to in common as the Majority Text, Byzantine Text, Antiochan Text, Authorized Version, etc.
What you have to do to be convinced of the corruption of the modern translations is to do a survey to see the evidence of meaningful changes, and conclude it is systematic and deliberate. The reference works below, compiled by Les Garrett, will help you accomplish such a task. His videos are on Youtube. Also recommended is New Age Versions by Gail Riplinger, which is much like Garrett's book below. The NIV, marketed by said Rupert Murdock, is being exposed for its departure from the fidelity of the Textus Receptus.
