To anyone reading this thread who is NOT bigoted, and who is more interested in the "truth", than in trying to score meaningless, "truthless" points in a senseless online argument, here are some links to sources giving some authentic Catholic views and insights pertaining to the Gospel of John, as well as some links to obtain some related resources. May these links prove to be a genuine blessing for someone.
You mean the rest are also sophists like the bigoted Scott Hahn? See posted material of his refuted on FR , by the mercy and grace of God. Invite him to debate here.
Then you have required notes in official RC Bibles, and many in the NABRE are quite liberal (though not all, and many are good) including as re. the authorship of John:
Other difficulties for any theory of eyewitness authorship of the gospel in its present form are presented by its highly developed theology and by certain elements of its literary style. For instance, some of the wondrous deeds of Jesus have been worked into highly effective dramatic scenes (John 9)
the accuracy of much of the detail of the fourth gospel constitutes a strong argument that the Johannine tradition rests upon the testimony of an eyewitness. Although tradition identified this person as John, the son of Zebedee, most modern scholars find that the evidence does not support this. - http://www.vatican.va/archive/ENG0839/__PX8.HTM
In any case, your list of converts to Rome is sadly a list of deceived souls none of whom can claim that the RCC is the NT church, since distinctive Catholic teachings are not manifest in the only wholly inspired substantive authoritative record of what the NT church believed (including how they understood the OT and gospels), which is Scripture, especially Acts thru Revelation.
As a former devout practicing RC, who spent about 6 years of never missing a Sunday after I became truly born again, I do know of the different in life and in doctrine btwn her and Biblical evangelical-type faith. Thanks be to God, though i need much more progress in heart.
HMMMmmm...
