Honestly, in my opinion is that the primary things to look for in a church are:
1. Teaches that the Bible is infallible, complete word of God.
2. That teaches that Jesus Christ is the ONLY way to salvation and everlasting life in Heaven.
3. That believes that the great commission of the Church is to spread the "Good News" of Jesus Christ.
4. All doctorine is firmly based in the Word of God (Bible - see #1).
As far as the differences are concerned - there are many, althogh most are fairly small and are simply based upon worship style and such.
I have only been associated with the Baptist church (actually Baptist Missionary Association of America) for about a year, previously being an Episcopalian, so my experience is still quite limited. The only direct doctrinal difference that I have experienced (although I am certain there are many more) is in the definition of " speaking in tongues".
I hope that others with some real knowledge post here to help you out, as I fear my post isn't all that helpful.
Good luck, and may God bless your life.
hello, I have a similar question...I recently relocated to a different state. I am pentecostal, and I speak in tongues, I also believe that God is our healer. This is my question, I have been attending a Baptist church for a few weeks, I have always been involved in church, they don't believe that tongues or that healing is for today. I have a little problem with that...not so much the tongue thing, that's is given to me, but healing is for everyone, because I have a problem with this issue, should I try finding another church or keep attending. thanks for any help.
