Well, just imagine for a second that the Bible would still be available in Latin only. Some priests with knowledge of Latin could then read and interpret for us, but we would be absolutely dependent on what they taught. If they were to say that we need to run and walk over the continebt of Africa to pay for our sins, we would have to accept it. If they say that the rich could make a big donation and then pay to send another in their place to make this tough trip, we would have to believe it.
Luckily the Bible is in English, but again there are many versions spanning from King James Version (more difficult to read) on the one hand to the Message (easy read) on the other hand. Again the bible has been written in a certain context and if we do not understand the context we may ask the ladies to wear a hat going to church or not to speak at meetings at all. Again you need a certain knowledge to understand a bit better.
If the Bible is indeed a letter written to the world, then we need to understand the bible very well to be able to explain and live the “instructions” where applicable. So you need to find a way to get to know better. There are quite a few online bible courses that you could follow. There are also meetings where the bible is explained better. Find time and fidna way to increase your understanding, otherwise the Bible could still be “Latin” or “Greek” to you.
