....."Faith" is the English translation of the Greek word pistis. Pisteuo "believe" and pistis "faith" are basically the same word. One is the noun form (pistis, faith) and the other is the verb form (pisteuo, believe). Here is a sampling of passages that use the verb form: Matthew 18:6; 21:32; Acts 8:37; 16:31; Romans 3:22; 4:11; 4:24; 8:37; 10:9.
Acts 16:31 is clear, concise, and to the point:
Acts 16:31 "Believe in the Lord Jesus, and you will be saved, you and your household."
With the verb form being used it basically means, "use your faith."
I like that, “use your faith”.
You will notice that these verses strongly support sola fide.
I checked the passages, and I'm not trying to be difficult, but I fail to see whether it's noun or verb form how it refutes the plain statement of scripture that justification is not by faith alone.
The Philippian jailor is one of those cases in the scriptures where there's no indication given of God's having wrought within beforehand, as with Lydia in vv 13,14 who was at a place of prayer on the sabbath and whose heart the Lord opened to receive the gospel, or as with 'devout' Cornelius in Acts 10, or the Ethiopian eunuch reading Isaiah in Acts 8, or the 'devout' Jews in Acts 2, etc.. I don't know if he even fully understood what he was asking, “Sirs, what must I do to be saved?” I have to presume that he knew that these two (Paul and Silas) were 'saved', and that they preached a way of salvation, and it had to make an incredible impression on him to witness these two praying and singing hymns to God at midnight after being whipped, cast into prison, and placed in stocks, and the prisoners listening to them; and to top it off, nobody ran when they had the chance! I believe his question to be along the lines of,“Sirs, what must I do to obtain this great joy that you possess?” Which brings us to:
"Believe in the Lord Jesus, and you will be saved, you and your household."
The intent of 'you and your household' is not relevant here (interesting topic though), so let's ignore it:
“Believe in the Lord Jesus, and you will be saved.....”
'Use your faith' in the Lord Jesus, and you will....what? Be saved from hell? Be given the free gift of eternal life? Be born from above? Apply the blood of Jesus and receive eternal redemption?
[I think] that Reformed 'Sola Fide' types generally take it to mean:
'Use your faith' (gift from God) in the Lord Jesus, and thereby apply the blood of Jesus and receive eternal redemption.
The passage is referring to salvation and not [only] justification. I don't know how you relate salvation to justification, sanctification, and glorification. To me, salvation consists of the other three, and has eternal and temporal aspects. Concerning the eternal aspect of salvation man is totally passive, with the temporal aspect he is active.
The types given in the scriptures contradict the notion that eternal redemption is acquired through 'sola fide':
“For our passover also hath been sacrificed, even Christ” [1 Cor 5:7].
On that dreadful night in the land of Egypt it was the father who slew the lamb and applied the blood, the firstborn was passive. The faith of the firstborn had nothing to do about whether the blood worked or not [eternal salvation]. The firstborn's faith in the blood would have everything to do with how they rested that night, or any joy that was to be had for that redemption [(temporal) gospel salvation].
Most that were redeemed out of Egypt, the land of bondage, were refused entrance into Canaan, the sabbath rest of God, because of their unbelief, Moses and Aaron included. They were totally passive in their redemption from the land of bondage, but by their unbelief they were responsible for the toil and weariness of wandering in the wilderness for the remainder of their lives, and for being denied entrance into the land of milk & honey. It required their faith to enter into God's rest.
but hath now been manifested by the appearing of our Saviour Christ Jesus, who abolished death, and brought life and immortality to light through the gospel, 2 Tim 1:10
The gospel sheds light on life and immortality, it does not impart it. It is Christ who has abolished death and imparts life and immortality through the birth that is from above, in which we are totally passive:
who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. Jn 1:13
It is through obedience to the gospel that the living may enter into the joy, peace, and righteousness in the Holy Spirit, which is the kingdom of God. John 3 makes it clear that before one can enter into or even see the kingdom of God they must first be born from above.
Nowhere is human effort or participation even hinted at unless you want to make believing a work.
28 They said therefore unto him, What must we do, that we may work the works of God?
29 Jesus answered and said unto them,
This is the work of God, that ye believe on him whom he hath sent. Jn 6
Believing [reliance on, adhering to] indeed is a work, faith is a fruit of the Spirit, and I suggest to you that it actually requires as much or more conscience effort on our part to believe as it does to do 'by nature' the things of the law which has been written in out hearts. It is error to view believing and being saved as a one time event. It is something we must do throughout our lives. Regeneration, i.e. the birth from above or eternal salvation, is a one time event, a done deal; salvation is an ongoing affair throughout the believer's life.
for not the hearers of the law are just before God, but the doers of the law shall be justified: (for when Gentiles that have not the law do by nature the things of the law..... Ro 2:13,14
The story of the good Samaritan beautifully illustrates the above truth. It wasn't the priest or the Levite, who had the law and who were hearers of the law, that helped him who had fallen to the robbers. It was a Samaritan, one whom the priest and the Levite would consider to be a dog, who had compassion and proved to be neighbor to him that had fallen. The Samaritan did it 'by nature'. A God given nature.
Thus the truth of Jn 3:21:
But he that doeth the truth cometh to the light, that his works may be made manifest, that they have been wrought in God.
God had already wrought within, and these were already doing the truth 'by nature' prior to coming to Christ.
....The justification in James 2 is not regenerative or salvific in nature.....
But you consider a passage like Ro 3:28 to be 'regenerative' in nature?
