John L. Kraushaar soon came into contact with this movement and, finding that the aims and motives were identically the same as those which he had considered from his perusal of the New Testament, he sought God’s guidance in prayer and finally discontinued his association with the Church of England and joined himself with this company. As the result of the informal gatherings spoken of previously, small assemblies were springing up in all parts of the country, meeting regularly for the simple office which became known in New Testament language as the breaking of bread, following as closely as possible the practices of the early disciples. This took place every week and it became evident that these gatherings needed shepherding and oversight, and also that deeper teaching of Biblical principles was desired and necessary. But a salaried minister was considered contrary to Scriptural teaching, and so it became recognised that, as in the early Apostolic Church, those with the ability to teach were set free for the exercise of this particular gift and were to depend on the resources of God’s bounty, their requirements to be made dependent on the voluntary gifts of the circle that was immediately benefiting by the exercise of their ability. George Muller, that grand pioneer of the life of faith and dependence, was beginning his work among the orphans of Bristol and launching further afield in establishing preaching centres in foreign lands. Simultaneously, Mr Anthony Graves, Lord Congleton and others were penetrating into Persia.
All these emerged from small assemblies, whose ideal had been to follow their Lord and the apostolic methods which received their commission from Him.
The London gatherings which had listened to Mr Kraushaar’s exposition of the Scriptures now suggested that he should devote himself entirely to ministering, and that some of the scattered assemblies about the country should be placed in his oversight, so that he should develop them and instruct them more fully. After prayer and consideration, he at once resigned his work in the London City Mission to enter upon a different kind of work in the county of Huntingdonshire. His work in the London City Mission had borne the most encouraging fruit, and he had founded a ragged school in a poor quarter of London which he now left established under the supervision of a convert.
