I & II Bully
The Apostle Peter wrote two epistles, one dealing with trouble from outside the Church and his other epistle dealing with trouble from within.
The Church, obviously, continues to experience trials and tribulations, both without and from within. One of these troubles is that of the ‘bully’.
Bullying is not limited to the children’s playground, nor non-religious activity. It is an exhibit of hubris that manifest itself quite well into adulthood, and not just outside the Church, but from within as well.
For those within the Reformed camp, you will want to take especial note of that second article.
