In his book Streams of Living Water, Richard J Foster suggests that sacramental living is manifest firstly through our corporate worship of our God and secondly through our material living.
There are many different ways people worship their God. We do it by using material and human forms whether by singing hymns or burning candles, dancing in ecstatic praise or bowing in speechless adoration. We also use the cross and a dove as symbols of holy presence. The sacramental emblems in the communion service are also a focus to lead us into God’s presence.
