Our mission is simple, be one make one.  2 Timothy 2:2 describes some of the apostle Paul's final words to his disciple Timothy when he said, "And the things you have heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others."  Being and making disciples is the mark of a missional church.

A more robust working definition of a missional church...the people of God living with the conviction that we are a sent people (by our Triune God) - called to be a faithful sign, foretaste and herald of the kingdom of God.  We are a people who engage in the task of "bilingual theological reflection (recognizing the grammar of the dominant culture as well as the grammar of God) so that we can embody the good news in the context in which we find ourselves and join God in the renewal of all things.

It sounds good to say, the church has a mission in the world.  However, that makes the church the primary acting subject.  The word missional has to be about agency.  It should be God.

The triune God's mission in the world has a church.  Now that places God as the primary acting subject.  Missio Dei.  "Missio"means sent.  In John 20:21, Jesus said to his disciples, "Just as the Father has sent me, I am sending you."  When we say we are sent by the Triune God, it looks like this: God sends the Son, the Son sends the Spirit and the Spirit sends the Church into the world.

In other words, we are to be like Jesus Christ in our neighborhoods, jobs, schools, city, state, country and the world, ala Acts 1:8).

Eugene Peterson's translation of John 1:14 is especially poignant when he writes, "The Word became flesh and blood, and moved into the neighborhood."  God moved into the neighborhood, and so must the church for the sake of the world.  

Jesus said in Matthew 16:18, "And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it."

One of the tenets of our tradition (Reformed) is the priesthood of all believers.  It's bad theology to assume that  one person (the pastor) delivers ministry.  We want to cultivate the gifts of all people.  We want to empower God's people to do ministry with the gifts God has given to each person.

A missional church is a church that sees mission as being not just one part of what the church does.  Instead, the church's mission shapes and forms its identity, lifestyle, strategy, priorities, spending, leadership, structure, and decision-making and has a focus on missional outreach.  This mission is based upon the life and mission of Christ: seeking the lost, serving the community, and sharing the good news, the story of redemption.  These three elements form a road map and guide for "missional outreach."
