I will say also that this is why it's important to read Marie's notes in the manuals, which I've found over the years that some moms tend to skip. I think she does an outstanding job of adding in the biblical worldview where it's missing and giving us things to think about and discuss with our children. She will often mention a passage in a book (not just SOTW, but any book) that might seem to conflict with a biblical worldview, or different doctrinal positions, and encourages us (and our students during the high school years) to discuss these issues with "your parents" or your pastor. At the high school level, the students are learning how to properly deal with the onslaught of choices they will be faced with in college and the real world, beginning with an argumentative paper in Week 1 of 9th grade, biblical analysis, literary analysis, and comparing the futile worship of false gods that man often chooses over the blessed worship of the One True God.
I also appreciate the fact that MFW uses so many different resources from different publishers. I think this helps to build a *truly* biblical worldview, because we ARE getting the perspective of numerous different people through the years. It teaches our children that no one author has all the right answers, except for the inerrant Word of God, and yet, some
versions of the same story actually might all
be true. (Think of the four Gospels in the Bible, for example, and how each of the Gospel writers told some of the same, and some different, details about Christ's death and resurrection.) Someone with a large family who lives in a small town in the rural midwest is likely going to view an event very differently than a single person who lives in the heart of New York City, kwim? Particularly if that event affects each of them in different ways. But they may both be telling the truth.
This method also teaches our children thinking skills and research skills. Consult multiple sources, the Bible being one of them, and prayerfully seek the Lord's will for your life, for your children's lives, and for what He wants you to know, and then what to DO with that knowledge.
Line up *everything* you read with what God says, take a look at the Big Picture, and put it in perspective. That's what MFW does, and they do this from the perspective of a family who's lived in Russia as missionaries, raised 6 children, has been deep in the work of Bible translation for many years. They've seen a LOT, and from various perspectives as they've lived in different parts of the country (U.S.) and the world, so they books they choose and the teaching commentary in the manuals, come from that very global (and biblical) worldview.
I do understand your concerns about SOTW, as I've had them myself. I have zero interest in ever using SOTW *by itself*. But put in the context of Marie's notes and the overall MFW program (their philosophy and goals through the years), I think they're a fine choice.
