The differences between what I believe and most Baptist churches were minute. As for labels, I'm not trying to be ecumenical. I hold that there are fundamental ("critical" or "essential") doctrines then there are other doctrines that are not essential to salvation. The ones that are essential:

1. The Bible is a Christian’s final authority. Without this fact being established, it all becomes a matter of opinion. God doesn’t have “opinions”.
2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.

2. We are all sinners
Romans 3:23 For all have sinned, and come short of the glory of God.

3. God Himself provided a way for us to get saved from sin and saved from judgment
Romans 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

4. And we can have assurance of being saved
1 John 5:11 And this is the record, that God hath given to us eternal life, and this life is in his Son.
1 John 5:13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.

5. It's the blood of Jesus Christ that washes away our sins
Revelation 1:5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood...

6. Because of this, we will be with Jesus forever
John 14:3 (Jesus speaking) And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.

7. Because of what Jesus did, we miss Hell
John 5:24 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.

8. There is only one way to Heaven
John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

This is worth contending for. Not just to be accurate, but to win those who are on their way to Hell. Remember:

Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.

I'm supposing you're referring to the doctrines of eternal security and gifts of the Spirit. Knowing how Baptists believe (I used to be a Baptist), I didn't think it was necessary (while pastoring the SBC church) to aggravate a person just to be right about my point of view. I wanted to convince them of the truth, not just prove myself right. I never did hide it, it just didn't seem necessary to be obnoxious about it. If I was going to aggravate someone, it would be concerning the fundamentals I mentioned above and calling sin sin.

As for eternal security, I believe closer to what Baptists believe. My contention is nobody has to be saved if they don't want to be. A "debate" I had with an atheist, the atheist said he used to be a born again Christian, attended Bible college and was a Christian for many years (and he believed all the essential doctrines and did evangelistic work) until his tour in the navy supposedly "opened his eyes to the truth" and he stopped believing in God. To say he is still saved would be a problem since he no longer believes there is a God. And, to say he was never saved in the first place, that would be closer to Roman Catholic doctrine. He said he repented of his sins, prayed to receive Jesus Christ as Lord and Saviour. If he wasn't saved in the first place, how do we know that? If we were to have met him before he became an atheist, we would have called him our brother in Christ.

So, you see, it is those two areas of contention that are the differences between me as a Pentecostal and most Baptists (I say most because of the doctrine of predestination is held by some Baptists and I believe the predestination is for Christians as described in the following verses:

Romans 8:29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
Romans 8:30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
Ephesians 1:5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
Ephesians 1:11 In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will...

...and NOT that some are ordained to be saved and other are not).

In this thread, I'm trying to get away from arguing about the gifts of the Spirit because it isn't getting anywhere. Where churches are dying is their replacing God's Word with a counterfeit.
