Wearing Pagan Symbols as a Christain?

Catholicism has no connection to Christianity. The Catholic Church is based entirely on traditions of the Catholic Church, which are identical to pagan images and practices. Christ is just one of their pagan images. For a long time Catholics officially discouraged studying the bible because so much of it disagreed with Catholic pronouncements. A lot of people were brutally murdered for trying to publish a bible in English.

So you probably know almost nothing about the Christian scriptures, not much about Catholic teachings, and nothing at all about pagan customs. You are a helpless waif and you want some pretty jewelry or something. You really should learn this business that you think you follow. First, choose who or what you follow. If Catholicism, get your advice from the priest, not strangers on the internet. If pagan stuff, you are on your own. If Christianity, study the bible and ignore the baloney that people try to tell you it says.

It is not reliable to ask people to tell you what the bible says. Many people will make up stuff because they don't know what it says, and many will make up stuff because they wish it would not say what it says. You just have to read it for yourself. Read a chapter of Proverbs every day. Proverbs has 31 chapters so you can keep your place by just looking at a calendar. There is no religion or nothing in Proverbs and you don't have to believe anything. Just read to find comfort and confidence. When you are comfortable with that, then read the bible from Romans to 2 Thessalonians over and over until you start to remember what it says. That is the part that applies to Christians. Here is a book to help you to understand the bible. It's a free download and you can get a hard copy at any bible book store.
