Uncoupling Apologetics and Evangelism

Apologetics has an interesting recent history, especially in the US. There have been some trends stretching back to the Second Great Awakening, and then other trends that kicked off in the 20th century (related to but not synonymous with the rise of fundamentalism) where apologetics and evangelism has had a large priority and focus, especially as "the mission of every Christian". Think of all the university-based Christian groups, where students might see themselves as "missionaries" to a secular campus. You can imagine in that context, "apologetics" would be seen as a way to interact with non-Christians.

This might be a majority view, but this is certainly not the only game in town, or how "Christian groups" have always seen their priorities. For example, there are currently some university-based Christian groups that are not "evangelism-focused", but rather "Christian-focused", as it were. That is, they are meant as a place for Christian fellowship, in a place where regular church attendance is difficult. So you can imagine that in THAT context, Christian students might be faced with difficult information, or even outright hostility, concerning their faith. So in that context, "apologetics" would be for Christians themselves, providing support and context for their faith.

So TL;DR: both sides of "apologetics" in the OP are pretty common, though often in different contexts. It's probably obvious from how I presented the information, but I am a strong supporter of the latter view above, that Christian groups are most effective when their priority is supporting Christians, whether apologetics or anything else.

I actually love apologetics, and in my youth I prioritized it, but these days I'm very much in favor of de-emphasizing it, with regards to evangelism. Christians are better evangelists by showing a genuine interest in the lives and cares of their non-Christian neighbors, than by constantly getting into intellectual head-butting with them (or feeling obligated to answer every challenge that others put to them). So I think that apologetics is best-suited to help Christians (especially new ones), many of whom aren't equipped (or taught by their churches) how to answer common challenges to their faith.
