I have mainly attended Presbyterian churches. I consider myself to be a Protestant but not a member of any organized religious group. I read and study the Bible and commentary on it but hardly consider myself to be an expert on Christianity.
One time I attended a Catholic service in the St. Louis Cathedral on Jackson Square in New Orleans. I was definitely impressed. The Priest devoted his sermon to condemning the French Quarter and its bars and entertainment in New Orleans. In the Protestant sermons I have attended I have rarely seen topics discussed that would directly target the audience as much as this Priest did as Jackson Square is in the French Quarter.
Most Protestant churches I have attended have sermons on the Bible and the lessons it teaches but avoid addressing the sins the congregation is committing to any great extent. For example in a small town in Ohio with few blacks you might hear a sermon on racism but not one on infidelity. It seems to me to object is not to irritate the congregation as they might leave and no longer contribute to the church.
I personally feel the main object of Christianity is to believe in Jesus Christ and his teachings and the fact he died to pay for our sins to prevent us from suffering an external death.
I believe the main rules of Christianity are covered in Mark 12:30-31.
30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’[a] 31 The second is this: ‘Love your neighbor as yourself.’[b] There is no commandment greater than these.”
I believe faith is more important than works but if you are a true Christian you will produce some good works.
I believe there is only one unpardonable sin.
Mark 3:28-29
Truly I tell you, people can be forgiven all their sins and every slander they utter, 29 but whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin.”
Many varieties of Christianity contain a lot of rules. While I could be wrong, I serious believe Christianity is a KISS religion (Keep It Simple, Stupid.) If for example your religion forbids dancing and watching movies that’s fine for you but others will not go to hell if they dance and watch movies as
long as they believe in Christ.
