After I know this how could I leave the church?

[Undeceived]

Sadly for our poor, bemused jesus freaks the very usage of the term Syria Palestina by Tertullian constitutes an anachronism by which we can date this particular piece of holy horseshit.

As noted here, the term Syria Palestina dates from 135 and was coined by the Roman emperor Hadrian upon the crushing of the bar Kokhba rebellion. "Tiberius" had been dead for nearly 100 years before the name was invented to do away with "Judaea."

In short, what Tertullian wrote is what we today call fucking bullshit.

Tertullian wrote "Syria Palestina" after it became the official name of the region. Isn't that just like saying Russia was involved in WWII? Technically the land was the Soviet Union, but we all know it as Russia today.
