Every Church employs liturgy, even if they don’t call it that. We go through our liturgical rites and rituals as we worship, and many of them remind us of the more important things of Christian faith, but in the end they are just empty actions without the Holy Spirit helping us to infuse them with the blood and life of Christ. What is communion if we can’t remember Jesus in it, ingesting His body and drinking His blood as we partake of the elements? What is baptism but a refreshing dip without the Holy Spirit opening our eyes to the truth of Jesus, and being born again? If our liturgical actions become performa, and don’t include Jesus then they are nothing but dead works.
