Jesus speaks to Philip in John 14:8-10, asking, "Do you not believe that I am in the Father, and the Father is in Me?" and He emphasizes the essential disposition to believe in God and His divine revelation in John 14:11, saying, "Believe me, because I am in the Father, and the Father is in Me; but if you do not, for the sake of these works believe me." Furthermore, in John 14:12, He highlights genuine trust in God, stating, "Amen, amen I say to you, he who believes in me, the works that I do he will do also."
The initial aspect of holy faith contrasts with the ignorance found among the Gentiles, as illustrated by Isaiah in Isaiah 65:1, where it is written, "I was revealed to those who do not seek Me; I was found by those who did not inquire of Me. I will say, 'Here I am, here I am.'" Acts 17:30 reinforces this, declaring that God, having overlooked the times of ignorance, now commands all men everywhere to repent. As Paul states in Romans 15:20, he intends to preach the gospel in regions where Christ has not been named, to avoid building on another’s foundation.
The second facet of holy faith reveals the severity of disbelief, highlighting how those who reject the truth of divine revelation and mistrust its mysteries are lost. This group includes heretics and individuals consumed by carnal desires for glory, who interpret divine truths as mere fiction. The Scriptures reference these individuals in several passages. Acts 17:18 describes how some Epicurean and Stoic philosophers engaged with Paul, some branding him a swindler and others saying, "He seems to be a preacher of foreign deities," because he preached Jesus and the resurrection. Furthermore, 2 Peter 3:4 states, "Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation."
The third tenet of holy faith addresses those who possess mere historical awareness of divine revelation but fail to add hope in God and His beloved Son. This superficial belief is no different from the desperate faith of the wicked or that of demons themselves, as articulated in James 2:19: "You believe that there is one God, you do well; even the demons believe and tremble," all of whom lack saving faith.
