Christians like to claim we are peaceful, sadly we are not.
If you want to witness heated debate, parliament is a good place to find it. If you want to see nasty, divisive debate, go to a church meeting or poke around on blogs written by Christians. The current hot potato is gay marriage, though women in ministry seems to also be ranking high in certain sectors, and in the US gun control is good to get a reaction.
These are all issues which should be discussed and even debated within the church, but why do people become so astonishingly nasty in their words and even actions over mere issues when we are supposedly all united in Christ?
Reading Philippians 4:7 would make me assume that Christians would be able to enter discussions about even contentious issues with a deep peace that regardless of the discussion outcome they remain secure in Christ:
And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. (Philippians 4:7 ESV)
This is particularly appropriate given that Paul introduced this paragraph pleading for some Christians to reach agreement on some divisive issue between them:
I entreat Euodia and I entreat Syntyche to agree in the Lord. (Philippians 4:2 ESV)
Instead of agreeing, it seems that many folks take this example of disagreement in the ancient church as license to foster disagreement in the modern church. Perhaps our problem is a lack of rejoicing in the Lord, and failing to let turn over our anxieties to God in prayer?
Rejoice in the Lord always; again I will say, rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.(Philippians 4:4–6 ESV)
