Written in 1927 as a follow up to his Missionary
Methods, the following was penned in the forward by Kenneth Grubb in
1960:
"It is only gradually that Roland Allen's Spontaneous Expansion of
the Church has established its reputation among those who are concerned with
the mission of the Church. This is odd since it is in many ways both a more
mature work than Missionary Methods: St Paul's or Ours? and also more relevant to the particular
tasks with which churches and missions have to wrestle today. Nevertheless, the
fact that a new edition is called for at the present juncture is, perhaps, a
recognition that the book contains much that needs to be said and read just
now."
What Allen was calling for 80 years ago and affirmed in the decades to follow
has "a lasting validity, and can be studied and re-studied with profit."
