Later that year the congregation at Honor Oak all agreed to leave the Baptist denomination (see Church Notes in the 1926 A Witness and A Testimony magazines).
[4] Together with like-minded Christians, he established a conference and training center at Honor Oak in southeast London.
There was a similar conference center maintained during the summers at Heathfield House in Kilcreggan, Scotland which was owned by Honor Oak Christian Fellowship.
[6] From the Honor Oak Christian Fellowship Centre Mr Austin-Sparks and his co-workers ran a publishing operation that printed a bi-monthly magazine, A Witness and a Testimony.
The first page of his magazine included the following statement: The object of the ministry of this little paper, issued bi-monthly, is to contribute to the Divine end which is presented in the words of Ephesians 4:13 - "...till we all attain unto the unity of the faith, and of the knowledge (literally - full knowledge) of the Son of God, unto a full-grown man, unto the measure of the stature of the fulness of Christ: that we be no longer children..." It is not connected with any 'Movement,' 'Organization,' 'Mission' or separate body of Christians, but is just a ministry to "all saints."
[11] This enabled him to work closely with several well-known Christian leaders in the UK and other countries, including Bakht Singh of India, Watchman Nee of China, Roger Forster of Forest Hill, Stephen Kaung of Richmond, Virginia and Lance Lambert of Jerusalem, Israel.
A colleague of his, Harry Foster, wrote: "Mr. Austin-Sparks had left word that there should be no automatic continuation of the magazine ministry".
