Saving faith in Jesus Christ alone for the work HE has accomplished. Being truly repentant (not just sorry, but actively turning from sin). This is what the most prolific apostle recorded time and again.
Anything beyond that should be the natural outpouring of our faith and salvation, because of our growth in Christ and the indwelling of the Holy Spirit in the believer. This includes all of the works and the fruits of the Spirit. James wrote of demonstrating our faith by our works - again, as a clear picture of a person who has received salvation through faith in Jesus Christ - should demonstrate their faith by their actions and works (not, again, a reliance ON works -but as a sign OF that faith).
I won't take away from people who feel the need to have itemized doctrine as a security blanket, just so long as they don't mistake a head-knowledge of such lists as what saves them.
My faith also trust completely Paul's first letter to Timothy - when he reminds the young pastor that "For there is one God, and one mediator also between God and men, the man Christ Jesus, who gave Himself as a ransom for all, the testimony given at the proper time."
**My faith also trust completely Paul’s first letter to Timothy**
Pretty narrow reference there. No Gospels?
Holy Scripture is only one part of a person’s faith. Do you obey the Ten Commandments?
Do you say The Lord’s Prayer?
Do you say either the Apostles Creed or the Nicene Creed at your church?
What church do you belong to that you base your faith on First Timothy only?
