The only way you are not aware of the problems that come with cliques forming in a community is if you have been living under a rock. Even if you have forgotten or blocked out your time in middle and high school, you have almost certainly watched a movie portraying those periods in a person’s life or heard about friend troubles at school from someone of that age. One of the most common, pervasive and enduring problems is that of cliques, small groups of friends that either actively exclude others or refuse to give others a chance to join their circle. Such cliques are most commonly thought of as a problem reserved for middle and high school girls, but adults are almost as quick to form cliques as teens and preteens. Churches are no exception to this. There are plenty of churches out there where it is very clear that the only people invited to brunch after church are those who are in music ministry or that the only people who talk to each other at the potluck are those who have been attending the church since they were children. Everyone else is given the cold shoulder. This is not an environment which fosters a Christian life or encourages Christian fellowship. Leave the high school drama behind, and find another church.
