Many claim there are secret codes in the Bible and numbers with hidden meanings and powers. This is one of the oldest heresies in Christianity, known as gnosticism. Such conspiracy type theories make people feel smart and special, but they are actually nonsense that leads to grave error and sin.

Not only is it gnosticism (I hadn't thought of that), but it is silly even to attempt it.
It's only my opinion, but if one wanted to search for codes, one would need the original manuscripts in order to do this research properly. And the original manuscripts are lost forever, so let's just trust the judgment of the ordinary Magisterium of the Church.
