"An ignorance of the Scripture is ignorance of Christ" -St. Jerome. It's okay, just start learning all you can. If you weren't able to tell the difference between western culture and the Bible than tell some friends , teachers & maybe your self- help guru's to stop quoting famous people as if they are in the Bible and start quoting the actual Word of God correctly. Also, we all must Pray and read to discern for ourselves by the guidance of the Holy Spirit to truly know what the difference is.
