"Keep on Seeking, and you will Find"
Hint: "First plucked from a tree guarded by a snake, it's powers perform miracles. Then, worn across the ages, torn asunder, hidden under a sea of red, reconstruct the time-line." You don't have to select them in a certain order (or at least, we don't think we do). Regardless, this is how we listed the paintings basing it off of the hint about "red" -- we selected paintings with red in them for the correct solution:
1) Christ Disrobed, Jerusalem. c. 30
2) Joseph, Egypt. c 1700 B.C.E.
3) Jesus Christ, Jerusalem. c. 30
4) David and Goliath, Valley of Elah. c. 970 B.C.E.
5) Jason, Greece. Prehistory
After solving the painting it's another photo-hunt with a painting of Jesus on the cross. Look on the right hand side of the painting for the solution.
