We can depart from the faith, this scripture shouldn't just be deleted from the bible.
1 Timothy 4:1
Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons,
1 Timothy 4:1
Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons,
1 Timothy 4:1 - Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, 2 speaking lies in hypocrisy, having their own conscience seared with a hot iron, 3 forbidding to marry, (that sounds familiar) and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth.
Obviously you believe that "depart from the faith" means that born again believers depart from saving faith in Christ and lose their salvation. (I find it interesting that NOWHERE in the Bible do we find the specific words, "lose or lost salvation.") The words "the faith" (Greek tês pisteôs) in this context means the apostolic faith, the New Testament apostolic body of doctrines. Some who are in a state of professing adherence to the apostolic faith, nevertheless will in both doctrine and practice depart from it, giving heed to deceiving spirits and doctrines of demons.
Some "nominal" Christians will abandon the Christian faith, the New Testament apostolic body of doctrines for false religions and cults. That does not prove such people were previously born again. In 1 John 2:19, we read - They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us.
I believe the beginning of such a major departing from the apostolic faith was evidenced as the Roman Catholic church came into power in the early 4th century. The Roman Catholic church forbids its clergy to marry and has other demonic doctrines such as transubstantiation, purgatory, indulgences, papal infallibility, Mary's perpetual virginity, works salvation etc..
