Nomenclature means the term or terms applied to someone or something, example: ‘customers’ was preferred to the original nomenclature ‘passengers’. In other words, the faith of Christ is also known as Mid-Acts Pauline Right Division – one can actually say they are synonyms.
So one has to believe Mid-Acts Pauline Right Division in order to have faith IN Christ’s finished work on the Cross, because the gospel of 1 Corinthians 15:1-4 is to be found in Pauline nomenclature which tells you what the gospel is and what to believe in order to be saved.
The faith of Christ (which is God’s righteousness without the law) is exclusive to what Paul preached in comparison to the 12 Apostles who preached that one is not only justified by faith, but by works too.
If you believe Pauline nomenclature you will also believe 1 Corinthians 15:1-4 and be saved which is faith in the faith of Christ.
Mid-Acts Pauline doctrine is a FAITH, namely the faith of Christ.
In Titus 1:1 the Apostle Paul calls it the faith of God’s elect:
Paul, a servant of God, and an apostle of Jesus Christ, according to the faith of God’s elect, and the acknowledging of the truth which is after godliness;
Whenever Paul speaks about the faith of Christ it is in contrast to the law, both of which are mutually exclusive to one another – Philippians 3:9:
And be found in him, not having mine own righteousness, which is of the law, BUT that which is through the faith of Christ, the righteousness which is of God by faith:
And in Galatians 2:16:
Knowing that a man is not justified by the works of the law, BUT by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Compare the fact that we are justified through the faith of Christ to James 2:24 which is doctrine to Israel in times to come:
“Ye see then how that by works a man is justified, and not by faith only.”
In times to come believers will be justified by the works of the law. Israel in times past (Old Testament) was also justified by the works of the law.
Two different nomenclatures, and to think most blend them today and perceive them to be one (nomenclature).
There are certain people who are under the wrong impression and who believe wrongly that everyone, including those living under the Old Covenant, as well as those who will be living during the tribulation were/will be saved by faith only.
Israel’s faith nomenclature (if I may call it that) has always been performance based = faith + works.
The fact that people are/were justified by works of the law confirms that they could/will lose their salvation when their works weren’t/aren’t in right standing with God, i.e., with the nomenclature given to them to believe in order to be saved.
