You are correct. 'True Christians', in Russell's view, existed in all churches. Heart unity and faith in Jesus, not the belief in a certain creed (WT or other), made a person a Christian. Disagreement with the WT in his day did not make one an apostate. We do see, however, how his original teachings were morphed into what they are today. Unity of heart and faith in Jesus were replaced by unity of belief (in the WT) and unity of faith (in the WT).
