I guess its just my catholic bible that is missing that part
It’s not just your Catholic Bible. You will not find Acts 8:37 in the main body of text of many modern protestant translations as well. For example, you will not find it in these modern protestant translations:
- The New International Version (NIV), which is the most widely used protestant text other than the King James Version (KJV), and the most widely used modern protestant translation.
- The New Living Translation (NLT)
- The English Standard Version (ESV)
My Catholic Bible (American Standard Version, ASV) likewise does not include this verse in the main body of the text. However the verse is marked as [37* in the main body, with the footnote noting:
The oldest and best manuscripts of Acts omit this verse, which is a Western text reading: "And Phillip said, “If you believe with all your heart, you may.” And he [the eunich] said in reply, “I believe that Jesus Christ is the Son of God.”
There are many ancient manuscripts of Biblical texts (none of which are original), and none of them agree. Some verses occur in one manuscript that do not occur in another. St. Jerome, who was commissioned by Pope Damascus to produce the official Catholic New Testament, the Latin Vulgate (still the official text today) scoured the land to find all the manuscripts he could find (none of which were original, even in Jerome’s time, an some of which do not survive to this day). He famously noted, with great frustration, “I have found as many versions as I have found copies.”
Modern linguists have access to all ancient manuscripts, and run them through computer software, along with other contemporary texts, to try to determine which passages are original and authentic. This is a science called “textual criticism,” although the name can be misleading because “criticism” has a negative connotation in English. Using these tools, modern linguists can produce better translations than St. Jerome, even though St. Jerome lived a very long time ago, closer to the time the Bible was written. We naturally assume that older translators, closer to the source, were better, but our modern translations are actually much better than anything that Jerome could have accomplished, and they get better over time as the science continues to evolve. A translation produced 100 years from now will actually be closer to the original text than anything we have today. Strange, but true.
So you will find this verse in older Catholic and protestant translations which pre-date the science of textual criticism, but not in modern Catholic and protestant translations with a scholarly basis.
The verse wasn’t “left out” of your Catholic Bible. The verse should have never been in ANY Bible. Your Catholic Bible (and modern protestant Bibles) correct this error.
