There are some modern hymns that are highly acceptable, such as “In Christ Alone”, “How Deep the Father’s Love for Us”, “We Fall Down”, and several more. When we sing those hymns in church, as opposed to praise ditties, there is a more palpable sense of worship in the place. Even if some of the theology is suspect—in my mind—there is a wonderful place for such theology in our worship. We are worse off if we eliminate it. My advice would be to institute a mix of true hymns, both old and new, even if some of the old ones need to be reset in modern dress.
