Found in a Vatican "junk box" the Sephardic Catalan Gospel of Mark, like Matthew, may very well prove the Gospels did indeed start in Hebrew. Not just because there are many Hebrewisms that "bled" through into English from the Greek manuscripts, but also because the Hebrew Mark solved a number of contradictions within the Greek manuscripts of the "New Testament". Among those, the Greek Mark claims the Gospel begins in the 1st Century while the book of Hebrews claims the Gospel began in the Wilderness with the Israelis. So which is it?
Revelation says the Gospel is eternal (implying past and future)!!
Christian scholars have spent volumes of books trying to explain the mental gymnastics they have done to make their Antinomian beliefs somehow fit the idea that the Gospel began in the 1st Century. But the Hebrew Mark solves all of that with ZERO justifications or mental gymnastics required. In life, the simplest solution tends to be the correct one. In matters of eternity, those which do not require human explanation tend to be the correct solutions.
Hebrew Mark may very well prove to be the most important of them all because of the contradictions it resolves that were created by the Greek Manuscripts.
