Doctrine (D-O-C-T-R-I-N-E-S) - tells us who God is, it tells us God's will, and it points us to our redemption from our sin nature.

The Two Kinds of Christian Doctrine: 1) Essential Christian Doctrine, is Doctrine that is essential to our salvation 2) non-essential Christian Doctrine, is doctrine that is not essential to our salvation.

"In Essentials Unity
In non-essentials liberty
and in all things charity."    this quote by Augustine, the father of modern theology is used in Christian Apologetics (defense) to guard and preserve Christian Doctrine.

D - Deity of Christ
O - Original Sin
C - Canon of Scripture
T - Trinity
R - Resurrection
I - Incarnation (of Jesus)
N - New Birth
E - Eschatology (return of Jesus and judgment of the world)
S - Salvation

NOTE: Study all the things on this page, and specifically memorize what the 
first 3 letters (D-O-C) of the D-O-C-T-R-I-N-E acronym stand for. You will be given a simple 
quiz within the next 3 or 4 days on things. I will want your answers and will let you know 
if they were all correct or will tell you the correct answer if you missed one. Next Sunday, 
lesson 2 will be posted on

In next Sunday's lesson (lesson 2), I will give a broad definition for each of the 3 categories (D-O-C). That will be lesson 2, and will be posted on Sunday, Nov. 24. Thanks, enjoy!
