How does the Baha'i faith justify the contradictions in the differing beliefs of Jesus' death?

When you really study the Baha'i Faith and research it (as I have) you see that even though at first glace it appears to be a very logical and reasonable faith, it's actually totally self-contradictory at its core and illogical. To them, religious truth isn't even real, it's just relative, so how do we know that the Bahai Faith itself is true if the Bahai Faith says that different faiths with contradictory claims are both true? The Bahai Faith is the most illogical faith out there.
