Acts 24:
[14] But this I confess unto thee, that after the way which they call heresy, so worship I the God of my fathers, believing all things which are written in the law and prophets:
 
One of the hindrances to sound Bible study is the use of 
man's modern definitions for God's Biblical terms. The word "heresy" is a case 
in point. How most people use this word does not line up with how it is 
used in the Bible. Generally speaking, most Christians think that heresy is 
simply any belief and teaching that is false. But if that is what heresy really 
is it would mean that all of us are heretics to some extent because we are not 
infallible. We will never be 100% right about everything we believe 
until we are glorified. The Bible is infallible but because of our fallibility 
it is always possible for us to misinterpret the scripture- regardless of our 
sincerity. I think that the words "heresy" and "heretic" are used 
entirely too carelessly and frequently. 
 
The first and only mention of the word "heresy" in the 
Bible (Acts 24:14) teaches us several important things about 
heresy:
•  It is a word that religious people love to use against 
those who do not follow their religious traditions. 
•   The apostle Paul worshipped God in a way that was called 
heresy by the Christ-rejecting Jews that exalted their traditions above the word 
of God. 
•   Being a genuine Bible-believer that follows Paul (1 Cor. 
4:16; 11:1) will make you a heretic in the eyes of religious 
people.
 
The plural word "heresies" is used three times in the Bible 
(1 Cor. 11:19; Gal. 5:20; 2 Pet. 2:1). The word "heretick" is used just once (Titus 
3:10). Studying these references will teach us what heresy really is and how we 
are to deal with it. 
 
We need to know what the Bible teaches about heresy so 
that we don't go around like religious ignoramuses carelessly accusing everybody 
that disagrees with us of heresy. God only gave one religion through Israel and 
the Jews corrupted it. The Body of Christ is NOT about religion but a real 
relationship with God through Jesus Christ (Col. 2:8-17). All religion today is 
of man and holds to traditions of men. Religious people love to 
accuse people that disagree with their views of heresy.
 
Down through history the roman catholic hierarchy has 
set up councils in which they have identified what they considered heresy. They 
have excommunicated “unrepentant heretics” (which to them means losing any hope 
of salvation) and they have murdered thousands of so-called heretics by burning 
them at the stake and other forms of torture. 
 
Protestants (groups that came out of the catholic 
religion) are labeled as heretics by the catholics but they too have labeled 
groups that disagree with their traditional beliefs as heretics. Protestants 
have been persecuted by the catholics but they in turn have also persecuted 
others. 
 
You may be thinking, "Well, at least the Baptists do not 
falsely accuse people of heresy". Sadly, that is not true. There are Baptists 
that promote what they call the "Old Time Religion" and hold to traditions that 
are not based on the scriptures, rightly divided. Many of them think that only the churches that 
are exactly like theirs are TRUE churches. They may 
not persecute those that they view as heretics but they certainly label and shun 
them. 
 
Our English word heresy is from the French word 
heresie. The word literally means "a choice", and by implication a sect, 
faction, or belief that one has chosen that is different from that which is 
commonly accepted. Thus, heresy can be any school of thought, although it is 
usually taken in the bad sense. A heretick is simply one who maintains 
heresy.
 
The same Greek word that is translated "heresy" is also 
translated "sect" five times in the KJB. According to Webster's 1828 dictionary, a 
sect is "A body or number of persons united in tenets, chiefly in philosophy or 
religion, but constituting a distinct party by holding sentiments different than 
those of other men." For example, the Saducees were a sect among the Jews 
that were united in their tenet that there was no 
resurrection.
 
According to how the word is used in the KJB, heresy is 
more than false doctrine. Heresy is holding to a false doctrine to the point of 
creating a faction or sect and thereby causing division (2 Pet. 2:1-2). 
 
While I am sure that the devil loves heresy and tempts 
people to be heretics, he should not get all the credit for heresies because the 
scripture teaches that heresy is a work of the FLESH (Gal. 5:19-21a). Notice how 
"heresies" is mentioned between "strife, seditions" and "envyings". 
 
Pride and the possibility of self advancement motivates 
those who hold to spurious doctrines to promote their views in an attempt to 
draw away disciples unto themselves and thereby forming a sect (Acts 20:28-30). 
 
Heresy, being a work of the flesh, is an ever present 
threat to any local church. The church at Corinth had heresies among them and 
Paul said that it must be so (1 Cor. 11:17-19). The positive thing about heresy 
is that it causes "they which are approved" to be made manifest because they are 
the ones who can answer and correct the heresy. Who are the approved (2 
Cor. 10:18; 2 Tim. 2:15)? 
 
In the context of 2 Tim. 2:15 we see that rightly 
dividing the word of truth will prevent us from heresy and enable us to identify 
and deal with heretics (v.16-18). 
 
How are we to deal with heretics?
•   Patiently instruct them in meekness (2 Tim. 
2:23-26)
•   If unrepentant after 2 clear admonitions, reject them 
(Titus 3:10-11)
•   Mark and avoid them (Rom. 
16:17-18)
