Next time you run into the presence or absence of a verse like Acts 8:37, don’t take it as a challenge or a conspiracy. The editors of the translation have good reasons for the path they chose and will usually leave a note to clue you in. With a little work, some consulting of textual commentaries, and some wider understanding of how thousands of manuscripts inform our understanding of the Greek New Testament, you can examine the evidence yourself and come to your own conclusion.
