Pietists Missional Approach

I believe that of the anabaptists, puritans, or pietists views of missions, the pietists practice of missions is the most theologically sound. They believed a lot of what the anabaptists believed, just without all the persecution of the views of the other churches. The pietists took what the church taught and went out by faith to simply tell people about the gospel. They saw that the Lutheran and Calvinist churches weren't doing it, and that the anabaptists form of "missions" was yelling at how the other churches were doing everything wrong, and that the Catholic system of power influence wasn't reaching the individual  in discipleship as it should, so they took the initiative to do missions in a way that was faithful in following the great commission. This would be the best approach for the church to follow today.
