In terms that I now incline to use, I could say that systematic theology and moral theology significantly overlap in their common concern for Christian self-understanding (i.e., = faith), while they differ insofar as they each also have to do with a distinct, albeit inseparable, aspect of Christian life-praxis (i.e., =witness), systematic theology having to do with the belief aspect of life-praxis, moral theology, with its action aspect.
