Theology 101: Introduction to Basic Ecclesiology
I once had a professor tell me to never use theological words when I happened to be preaching. I am sure you also received that advice if you attended xyz school for ministry. The only problem is that advice leads you and me down the road to theological immaturity. Yes, the Bible doesn’t use some of the big boy theological words that have been devised to convey it’s message. However if you are going to study law, it’s not enough to just watch Law and Order. You have to get a little down and dirty with the lingo.
I know this is not going to blow the socks off of all of my pastor/church leader/seminary friends, but I didn’t write it for them. I also will admit that what I am about to say is neither new or profound; but, if you love Jesus, you want to take it up a notch in the theological ladder, and impress your pastor next Sunday then read on...
Term: Ecclesiology
Origin (via Wikipedia): from Greek ἐκκλησίᾱ, ekklēsiā, "congregation, church"; and -λογία, -logia
Definition: Ecclesiology is the study of the church, asking what the church is. I wrote on this a while back here, if you care to time travel. In short, the church is the body of Christ (the Lord’s people) called out from among the world to be his people and bear his message back into all creation.
Thoughts: In my theological academic study I have probably thought about this question the most. In what many have termed to be the twilight era of Christendom, I want to know what it is that we should be doing as the church in the west (USA, Canada, Europe), and how we should be doing it. Even the what and how questions are preceded with a why question: why is there a church to begin with?
With this diagram I am taking the what question of ecclesiology down to it’s essence, this is what any church should be about.
The church exists to be a community of Christ-followers that worships God and also equips, trains, and helps people that love Jesus build relationships with people that don’t yet know Jesus. This is/should be the basic ingredient as to what we are about as the Church, as Christ-followers. It’s not about programs, bands, movies, it’s about building relationships. Every program, event you have should be about helping people the love Jesus connect with people that don’t yet know Jesus.
Throughout time the ‘church’ has grown, changed, developed, sinned, just like any human institution. sometimes we have taken our eyes of this basic understanding of relationship building (and always to our detriment).
Summary: Ecclesiology is the study of the church, who we are, why we exist, and what we are to be doing in the world.
