Checking out the Northumbria Community, we try to live by this rule.

Summary of the Rule of the Northumbria Community -
A Way for Living

This is the Rule we embrace. This is the Rule we will keep: we say YES to AVAILABILITY; we say YES to VULNERABILITY.

We are called to be AVAILABLE to God and to others:

Firstly to be available to God in the cell of our own heart when we can be turned towards Him, and seek His face;
then to be available to others in a call to exercise hospitality, recognising that in welcoming others we honour and welcome the Christ Himself;
then to be available to others through participation in His care and concern for them, by praying and interceding for their situations in the power of the Holy Spirit;
then to be available for participation in mission of various kinds according to the calling and initiatives of the Spirit.

We are called to intentional, deliberate VULNERABILITY:

We embrace the vulnerability of being teachable expressed in:
a discipline of prayer;
in exposure to Scripture;
a willingness to be accountable to others in ordering our ways and our heart in order to effect change.

We embrace the responsibility of taking the heretical imperative:
by speaking out when necessary or asking awkward questions that will often upset the status quo;
by making relationships the priority, and not reputation.

We embrace the challenge to live as church without walls, living openly amongst unbelievers and other believers in a way that the life of God in ours can be seen, challenged or questioned. This will involve us building friendships outside our Christian ghettos or club-mentality, not with ulterior evangelistic motives, but because we genuinely care.
