OBSERVATION - WHAT VENN SAW:
Nothing new -- a voice from the past.

HENRY VENN ON THE "NATIVE" CHURCH AND MINISTRY - THE GOAL

"Regarding the ultimate object of a Mission, viewed under its ecclesiastical result, to be the settlement of a Native Church under Native Pastors upon a self-supporting system, it should be borne in mind that the progress of a mission depends upon the training up and the location of Native Pastors; and that, as it has been happily expressed the "euthanasia of a Mission" takes place when a missionary, surrounded by well-trained Native congregations under Native Pastors, is able to resign all pastoral work into their hands, and gradually relax his superintendence over the pastors themselves, till it insensibly ceases; and so the Mission passes into a settled Christian community. Then the missionary and all Missionary agencies should be transferred to the "regions beyond." 

Henry Venn in Max Warred (ed) To Apply the Gospel  p26.

Here is the great danger, already recognized in Venn's time (1880s) and which we can observe in many mission areas where outdated missions strategies remain in force.

"This view of a native ministry should be kept in sight from the first commencement of a national church, otherwise the missionary will insensibly become the pastor, and the native teachers who may be trained up will be employed rather as missionaries than as native pastors, and will, as agents of an European society, imbibe European tastes and habits; instead of regarding themselves as ministers, or servants of the Lord of the native population with which they are to be in every way identified."

Venn in To Apply the Gospel p62.
