As a preacher, it is extraordinarily easy to get into the mindset that everyone must see every issue the same way you do or they are not Christians. The truth of the matter is that Christianity is decidedly not a homogenous mixture of people. The differences of background, descent, race, ethnicity, etc. are what makes us such a unique body of believers. This also means that there is very little unanimity on certain issues within the Church, for example, infant baptism. But somewhere along the way, we must realize that we are not the greatest theologians of all time nor are we even the greatest Christians of our time. We must come to the point that we understand that the brothers are all going to have differing opinions and beliefs when it comes to most topics.
Doctrine is one of, if not the, greatest tools of all time.It keeps out heretics and keeps God-fearing people within the Church from following the heretics. Doctrine is the necessary conclusion of theology. Theology is where we pound out what we believe and doctrine is the presentation of the finished product thereof. It is very important that we get both right according to the Scriptures. If we do not, we may fall into idolatry.
But, brothers and sisters, a warning: do not forget the love. We mustn’t forget that the point is that we love one another as brothers. There is a reason we refer to one another as such. Do not forget, as you dot your doctrinal i’s and cross your theological t’s, that the word you are spelling is CHRIST.
Matthew 5:22 (KJV)
22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
Do not, I implore you, refer to your brother as a fool.
