It amazes me how much time we waste in the church over matters of opinion and not the core of the Christian faith. What if we spent more time trying to make disciples of Jesus Christ instead of arguing about what color the carpet should be in the worship space, whether to have a Christmas Eve Service and a Christmas Service when Christmas falls on Sunday, whether gay people should be pastors or even members of the church, whether megachurches are the best form for doing church or whether we should have house churches, whether we refer to God as he, she or it. Just imagine if all the energy spent on these types of issues was spent feeding the hungry, clothing the naked, and helping persons to have a heart changing encounter with Jesus Christ. Praise God that He still uses us to do great things!! He is an awesome God!!!
I like what John Wesley had to say about controversies like the ones above. Wesley said quoting Augustine, "In Essentials, unity. In non-essentials, liberty. In all things, love." This doesn't mean an "accept every thought" type of thinking. Instead, it displays a willingness to be open to ,and to work closely with, those whom differ on such matters as worship and teaching that don't affect the essence of Christian belief. The essence of Christian belief would include such things as doctrines about the Trinity, who Christ was and what he did, the human need for God's grace and more. The non-essentials are things like those listed above.
Wesley was responding in his time, at the earliest stages of the Enlightenment, to the bloodshed caused by the wars of religion. I think we do well to hear these words again ourselves in Christianity. While we are not killing each other on the battlefield over opinions, we continue to wage bloody wars of words (on all sides!) that do advance the cause of Christ while people are perishing. Lord, have mercy.
