Don't be so open minded - 2 John

2 John 1:10

If anyone comes to you and does not bring this teaching, do not receive him into your house, and do not give him a greeting;

Christianity prides itself on being hospitable, amicable, and accepting.  You can turn to many passages in God's Word that even enforce and teach just guiding principles.   However, our societies pressure to make sure we "accept" all things and "abide" by all things is not a Biblical or Christian concept.  It is fostered from Satan, himself.   It is a lie from the Father of Lies.   In John's day, toward the end of his life, the church was fully under attack by false teachers and leaders who the god of this world was using to lead the People of God away from the truth.  The denied the Deity of Christ and the Work of Christ.   In John's day they were false teachers and were to be treated as such.  We are told today to not be "unloving" toward those who oppose our views.   We are to be open to the things of the world, especially different life styles and different views about morality and, even, ethics.   Yet, John was quite blunt and quite narrow minded in his views.  His warning to "his children" was that if someone denied Christ's came in the flesh (in other words, "Christ's Incarnation ... That He was fully God and fully man), we are not only to keep them out of our house, we are to not even greet them.   (The reference to our "house" would be another way to refer to the early church as they often met in the homes of believers to worship.   This letter in particular is to someone who is using their home for worship.)  We are not to be "open" minded to false teaching from someone who denies Christ is Lord and Savior of the World.   That includes "anyone" who rejects Him.   We can be civil and we can, like Christ, show forgiveness for ignorance.   But, we are not to open our minds to their teaching.   We are to stand our ground, which might not look very hospitable, amicable, or accepting.
