Incarnation os one of the two foundational miracles of the Catholic Faith (Resurrection is the other). It is in the nature of miracles to be confusing to the unbeliever. If we are to evanglelize the Protestants, and they are in dire need of evangelizaton, some confusion of their minds is unavoidable and further, it is salutary.
What exactly in your mind makes "us" Protestants (I prefer Christian, if you need a label, but for argument sake...) need evangelizing about? What is our "dire" need? I believe it is Catholics, or any other works-based religion, that need to hear the clear Gospel. That going to heaven when we die is not based upon how good we are but soley by the unmerited grace and favor of a loving God who asks us to accept by faith the free gift of eternal life he offers to us. Is getting us back to Mass more important than this???
