If that was the case then they must not have believed or were paying attention when Christ said "Go into all the world and preach the gospel to 'every' creature." And also when he said "this gospel will be preached in all the world and 'then' the end will come."
Either that or they must have had confidence in themselves to be able to preach to every person in the world (including such known places as Spain, England, Africa, and Asia) in their lifetime and while much of this area was controlled by the brutal Romans who had their own gods they built huge temples in honor of.
...And what do you mean "huge" {temples}? Take, for instance, the temple at
Elst in the Netherlands. One of the biggest north of the Alps, it only measured 23 by 30 meters. That's big, but not huge in my playbook.
The one Lendering describes there is the second temple on that site: the first was burned down during the Batavian Revolt of 69AD. The temple is remarkable because also because it gave archaeological confirmation of the suovetaurilia sacrifice consisting of a pig (sus), sheep (ovis) and bull (taurus), which was only known thus far from Roman literature.

I don't think a lot of people realize just how drastically Jesus and Christianity changed the world.
A good book on this topic is titled "What If Jesus had Never Been Born".
