When did we disavow Chambers?

[Blake]

I thought I remembered reading somewhere that Oswald Chambers was a Particular Baptist. I don't have my Complete Works of Oswald Chambers book to check it, but was surprised that there is no mention of him in Garrett's Baptist Theology: A Four Century Study or Brackney's A Genetic History of Baptist Thought and Historical Dictionary of the Baptists. When were his Baptist credentials revoked?

I don't know about disavowing him, but it appears that his entire public ministry was associated with the Holiness movement. His Baptist connection was through his parents (his father was a Baptist evangelist and pastor in Scotland and England) and his baptism and first church membership (in Rye Lane Baptist Chapel, Peckham); he effectively ceased to be Baptist somewhere between 1893 and 1905... How do I know all this? ! I haven't checked their sources...
