The ritual of Communion. Christian rituals are a two-way channel of communication, expressing the believer’s deepest hopes and prayers, and dramatizing God’s promises and warnings. Thus the rituals in the Lord's Supper are of the greatest importance. The prayers, the meal with the sursum corda and the doxology are rituals through which communication is expressed between the Holy Trinity and the congregation. In this holy communion each Person of the Trinity has His own place and works according to the pactum salutis and the economy of the covenant in the Holy Trinity.
