As we plant a new church in Windsor, Ontario, we have a rather unique and admirable opportunity to shape it well from the start.
In 1530, Melanchthon drew up the Augsburg Confession, which in Article 7 stated that “this church is the congregation of the saints in which the gospel is rightfully taught and the sacraments are rightly administered. And for that true unity of the Church it is enough to have unity of belief concerning the teaching of the Gospel and the administration of the sacraments.” In his Loci Communes (1543), Melanchthon repeated the idea: “The marks which point out the church are the pure gospel and the proper use of the sacraments.” Since the Reformation, Protestants have typically viewed these two marks – the preaching of the Gospel and the proper administration of the sacraments – as delineating the true church over against impostors.

So any church that is to be a church must rightfully teach the Gospel and rightly administer the sacraments. Check!
