True. A paradox is a contradiction that you continue to discuss, otherwise there is no discussion, the contradiction is simply discarded.
Most people who discuss religion prefer to discuss their doctrines as opposed to simply discarding them because there is a contradiction. Since contradictions are allowed in religion, thus enabling continued discussion, the contradiction can simply be called a paradox and the discussion continued without missing a beat. The Catholic Church does exactly this, except they don't use the word "paradox", they say "mystery" (or "great mystery", depending on the importance of the doctrine).
When a religious person is discussing religion, it isn't particularly helpful / useful to point to an apparent contradiction and say "Nope! False! That's a contradiction right there. Discarded." It is more productive to respond "That seems paradoxical, you claim one equals three, yet one does not equal three", etc. while continuing the discussion.
Of course, religious people discussing religion are free to use the word "contradiction" as long as everyone involved in the discussion agrees to interpret "contradiction" as "paradox" or else the discussion won't last long.
