Justification By Faith Alone: A Hill Upon Which to Die

Wanted to share a response I intended to give to someone who denies that belief in justification by faith alone is an essential doctrine. (Pretty much everyone who reads my blog knows who I am talking about). Consider these verses, and envision how Paul would react to the death of John Paul II and the immediate compromise of the Evangel by so called "evangelicals":

Galatians 1
6 I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel;
7 which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ.
8 But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed!
9 As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!
10 For am I now seeking the favor of men, or of God? Or am I striving to please men? If I were still trying to please men, I would not be a bond-servant of Christ.

Galatians 3
1 You foolish Galatians, who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified?
2 This is the only thing I want to find out from you: did you receive the Spirit by the works of the Law, or by hearing with faith?
3 Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh?
4 Did you suffer so many things in vain--if indeed it was in vain?
5 So then, does He who provides you with the Spirit and works miracles among you, do it by the works of the Law, or by hearing with faith?
6 Even so Abraham BELIEVED GOD, AND IT WAS RECKONED TO HIM AS RIGHTEOUSNESS.
7 Therefore, be sure that it is those who are of faith who are sons of Abraham.

Galatians 5
1 It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery.
2 Behold I, Paul, say to you that if you receive circumcision, Christ will be of no benefit to you.
3 And I testify again to every man who receives circumcision, that he is under obligation to keep the whole Law.
4 You have been severed from Christ, you who are seeking to be justified by law; you have fallen from grace.

Philippians 3
1 Finally, my brethren, rejoice in the Lord. To write the same things again is no trouble to me, and it is a safeguard for you.
2 Beware of the dogs, beware of the evil workers, beware of the false circumcision;
3 for we are the true circumcision, who worship in the Spirit of God and glory in Christ Jesus and put no confidence in the flesh,
4 although I myself might have confidence even in the flesh. If anyone else has a mind to put confidence in the flesh, I far more:
5 circumcised the eighth day, of the nation of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the Law, a Pharisee;
6 as to zeal, a persecutor of the church; as to the righteousness which is in the Law, found blameless.
7 But whatever things were gain to me, those things I have counted as loss for the sake of Christ.
8 More than that, I count all things to be loss in view of the surpassing value of knowing Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them but rubbish so that I may gain Christ,
9 and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith,
10 that I may know Him and the power of His resurrection and the fellowship of His sufferings, being conformed to His death;
11 in order that I may attain to the resurrection from the dead.

Romans 4
1 What then shall we say that Abraham, our forefather according to the flesh, has found?
2 For if Abraham was justified by works, he has something to boast about, but not before God.
3 For what does the Scripture say? "ABRAHAM BELIEVED GOD, AND IT WAS CREDITED TO HIM AS RIGHTEOUSNESS."
4 Now to the one who works, his wage is not credited as a favor, but as what is due.
5 But to the one who does not work, but believes in Him who justifies the ungodly, his faith is credited as righteousness,
6 just as David also speaks of the blessing on the man to whom God credits righteousness apart from works:
7 "BLESSED ARE THOSE WHOSE LAWLESS DEEDS HAVE BEEN FORGIVEN, AND WHOSE SINS HAVE BEEN COVERED.
8 "BLESSED IS THE MAN WHOSE SIN THE LORD WILL NOT TAKE INTO ACCOUNT."
