How should one measure the stature of a tree? Its girth in centimetres? Its height in metres? Jesus rarely measured anything quantitively, for him it was all about the quality. The stature of a mustard tree, quite clearly in Jesus’ mind, is measured by its ability to host nesting birds – to give them a place to be safe, to raise their young, and to fly home to.
If that is what the kingdom of God is like, and the church is in some way a sign of it, then can we be the kind of church whose stature is measured not by the number who attend, nor by the amount of money in the collection plate (good and helpful though these things are) but by our ability to provide an environment that is safe, that is nurturing, in which people can feel at home. In essence, for Jesus the kingdom of God is about hospitality. That’s maybe why after the mustard seed he goes on to talk about yeast – the stature of which is measured by its ability to raise a whole loaf, a loaf which can then be broken and shared with friends and strangers.
Our stature, then, as churches, might be best measured by our generosity – our ability to give, to share, to be given, and to be shared. We practice this each week as we share in Holy Communion, and seek to become what we eat – the Body of Christ, Christ who lived a life of hospitality, and enjoyed the hospitality of others, and who spoke of heaven as a sum of many dwelling places and as a great feast. May we embody the life of heaven here on earth and may our churches be more like the mustard seed and its tree, the yeast and its bread.
