I've been reading C. T. Russell's works. While he was far (far!) from perfect, one positive characteristic he did have was that he didn't use the term "apostates" the way JWs do. He didn't slap the label on those who disagreed with him or who didn't want to become Bible Students. I would take his words at face value, not as code for "anyone and everyone who disagrees with us."
In the interests of keeping myself honest, I looked up the magazine in question. The first quote in the OP came from an article dealing with those who opposed the Society, not by simply disagreeing, but by using specific underhanded and dishonest means of doing so. [http://www.agsconsulting.com/htdbv5/r4482.htm] Specifically, violent disagreements were erupting over the identity of "that servant" in Matt. 24:45. (Interestingly, nowhere in the article is it suggested that this be identified as Russell.) Concerning those who disagreed, the article states:
From the first we have urged that this subject be not allowed to produce contention or bitterness of spirit. Let each reach his own conclusions and act accordingly. If some think that they can get as good or better provender at other tables, or that they can produce as good or better themselves--let these take their course. All who feel dissatisfied with the spiritual food which our great Master has privileged us to send broadcast to every nation should certainly be looking anywhere and everywhere for something better. Our wish for them is that they might find something better. If we were dissatisfied ourselves, or if we knew where something better could be obtained, we certainly at any cost would seek it. And how could we find fault with others for doing what we ourselves would do? Rather let us bid them God-speed in their search for something more satisfactory.
While clearly believing the Society was publishing "spiritual food", they didn't insult the intelligence of those who felt they needed to look elsewhere via an ad hominem attack. The article doesn't even label those who disagree and leave "opposers."
It isn't until nastiness rears its head that the description of some as "opposers" is employed. The vitriol and unreasonableness perceived in the actions of such ones is likened to the madness of rabies. The full paragraph containing the first quote reads:
But while we are willing that others should go anywhere and everywhere to find food and light to their satisfaction, strange to say, those who become our opponents take a very different course. Instead of saying in the manly fashion of the world, "I have found something which I prefer; goodbye!" these manifest anger, malice, hatred, strife, "works of the flesh and of the devil" such as we have never known worldly people to exhibit. They seem inoculated with madness, Satanic hydrophobia. Some of them smite us and then claim that we did the smiting. They are ready to say and write contemptible falsities and to stoop to do meanness.
The word "apostate(s)" doesn't appear in this article. Actually, it doesn't appear anywhere in the Oct. 1, 1909 magazine, so I'm unsure of the source for the second quote.
