Paul who is famous for faith alone does not actually use the word Pistis or verb pisteuo to mean faith in facts alone except in 1 Cor. 15:1-4 and in Romans 10:9 and Romans 4:4-5. Otherwise, it is not clear (Eph 2:8-9) or otherwise an impossible meaning, e.g., Pistis of God (Rom. 3:3) or Pistis of Jesus / Christ (7 times).
We do an analysis whether Romans 4:4-5 is actually blasphemy to repeat today. Paul teaches God justifies the « ungodly. » All commentators are canvassed, and all agree (proudly) this means without any repentance ft,om sin, turning away from sin, and so on. But God in Exod. 23:7 says He does not « justify the wicked, » which in Greek Septuagint is translated as « arbse » — the same Greek word Paul uses in Romans 4:5 to say God « justifies the ungodly. » Hence, Paul says the opposite of Exod. 23:7. Also, Prov. 17:15 says anyone who « justifies the ungodly » is an « abomination » to the Lord YHWH.
Hence, Paul not only contradicts God, but says with Abraham, God forgave Abraham while he was still « ungodly, » unrepentant. I would not recommend anyone teaching this for this very much sounds like an insult on God that He would have justified Abraham despite Abraham still being an idolator and ungodly. God calls that elsewhere an « abomination, » and hence claiming God would justify an « ungodly » person is a deep insult on God, and hence a blasphemy.
