Tolkien was a devout Christian and an expert in mythology. He wasn't infected by the 'enlightened' western materialist mode of thought.

The materialist mode of thought has only existed for a few centuries. Your ancestors believed that ideas (the supernatural) were every bit as real as the physical (natural) things around you but exponentially more powerful since they are less bound by physical constraints and can transcend time, making them effectively immortal. They also believed that these ideas contended with one another for supremacy.

How do ideas survive? How do they contend with one another? How do they transcend time?

Why is the LOTR still happening? Because the Light is still at war with the Darkness. The Truth still contends with the father of lies. Humility is still the way to salvation. We are always awaiting the Return of the King.

Now ask yourself, who is the true King? Hint: I just told you.

Remember who you are and never give into fear.

Nobody in LotR got crucified though. 

Well, Isildur REFUSED to toss the ring into the mountain so its the anti Jesus moment.

You just said it yourself, the destroying of the ring is a sacrificial act symbolic of much the same as the actual crucifixion. The more fitting parallel in my opinion is that of the ring to the cross itself. The cross itself is a symbol of death, torture, and struggle. The ring is also symbolic of death, specifically degradation and greed. Jesus’ triumph over the cross/death is what sanctifies it/ gives it its holiness. But it itself is a symbol of doom. 
Speaking of which, Frodo carries the ring (cross) up Mt. Doom, stumbles and perhaps in the most obvious reference to Christianity, Samwise (Simon) helps him to bear his burden.
