1 Tim 4:1-4: Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron; Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
“that in the latter times some shall depart from the faith”
Protestants departed from the real faith in the 16th Century. I am no Francis fan, but the Catholic Church is the true faith. Popes come and go. Some good, some bad. Christ promised he would be with the Church always.
And the word translated "meats" in your KJV is the generic term for "food" in Greek.
The reference is to Gnostic groups.
