"Beware of false prophets, who, indeed, come to you in sheep's clothing, but within are ravening wolves.
for there will arise false Christs and false prophets; and they will give great signs and wonders, so as to lead astray, if possible, even the elect.
and from among yourselves will men arise, speaking perverse things, to draw away the disciples after them.
For those who are such are not serving our Lord Christ, but their own belly; and, through their kind words and flattering speeches, they beguile the hearts of the simple.
that we may no longer be babes, billow-tossed, and carried about with every wind of teaching, in the sleight of men, in the craftiness suited to the artifice of error;
2 Timothy 3:5
holding a form of godliness, but denying the power thereof: from these also turn away.
2 Peter 2:1
But there arose false prophets also among the people, as among you also there will be false teachers, who, indeed, will stealthily bring in destructive heresies, denying even the Master Who bought them, bringing upon themselves swift destruction:
for they are spirits of demons, working signs; which go forth unto the kings of the whole inhabited earth, to gather them together to the war of the great day of God, the Almighty.
And, as they did not approve the holding of God in their knowledge, God delivered them up to a reprobate mind, to do those things which are not becoming;
who, indeed, having become without feeling, delivered themselves up to lasciviousness for the working of all uncleanness with greediness.
