There is absolute truth, we just can't know it absolutely.

I.e., we're limited by our own cognitive imperfections and cultural worldview.

It's like the blind man that Jesus healed, the first attempted he saw people as trees walking. It wasn't until Jesus put his hands on his eyes a second time that he saw clearly.

Likewise we see the world dimly, but one day ours eyes will be opened. One can only hope they weren't too far off the mark.
