Which Logos Packages/Collection most closely aligns with the "Church of Christ" doctrine/viewpoint?
Depends on the version of Church of Christ, or church of Christ. I'd say Baptist, assuming you wanted the content.
Actually, cOC is spread thru-out the packages (doctrinally).
I agree that the Baptist packages would probably be closest in content. It really depends upon what packages you already have and what your specific needs are. I have found purchasing the standard upgrade to be the most beneficial for me. I compare from the starter package up. If the next largest package adds more to the cost than the individual books that I desire from that package would, I drop back to the prior level package. I can then purchase those books separately, or more likely wait for them to be on sale. This time, Logos 10 Silver along with the Full Feature Upgrade worked great for my needs.
With the acquisition of Wordsearch, Logos is slowly building a decent library of Restoration Movement books. I hope that before too long, they will offer some sort of Restoration Movement package.
