Concerning the sacraments

A trinitarian, incarnational understanding of the sacraments has significant implications for how we approach both baptism and the Lord's Supper. This issue is helpfully addressed by many trinitarian theologians. Here are two examples:

Paul Fiddes writes in Participating in God:
[We understand] the sacraments as pieces of earthly stuff that are meeting places with this [triune] God who exists in ecstatic movements of love. They are doors into the dance of perichoresis in God. [They are a means] of God’s gracious coming and dwelling with us. They are signs which enable us to participate in the drama of death and resurrection which is happening in the heart of God. We share in death as we share in the broken body of the bread and the extravagantly poured out wine, and as we are covered with a threat of hostile waters. We share in life as we come out from under the waters…to take our place in the new community of the body of Christ, and to be filled with the new wine of the Spirit (p. 281).
Graham Buxton writes in Dancing in the Dark:
Both sacraments [baptism and the Lord's Supper] declare the gospel of participation in the perfect worship of the Son, who has accomplished what we could not accomplish. When we receive the bread and wine at the sacrament of the Lord’s Supper, we echo the cry of Jesus on the cross: ‘It is finished!’ Christ has done what I could never do…But we do more than engage in a memorial service! The word anamnesis, which translates into remembrance, has rich meaning…[conveying] a sense of re-living the past as if it were real today….Not only do we participate in shared and thankful remembrance of Christ’s perfect self-offering on our behalf, but we also participate in Christ’s continuing self-offering of himself on our behalf. We do not remember just the Christ of history – we remember the living Christ today, and the Christ who carries us into the future…The sacrament powerfully draws past, present, and future together in the life of the faith-community (pp. 137-138).
