Sacraments convey grace, strengthen faith, enhance unity and commitment within the church, reassure us of God's promises. If the rubrics are followed but mistakes are made the sacrament does not lose its efficacy. Ex opere operato applies here. Efficacy of a Sacrament Anglicans views sacrament as bringing into effect what it signifies, not just memorials. Efficacy is tied to Christ's Real Presence in the bread and wine which in mystery becomes his body and blood.
Appointed conditions constituting the sacrament are duly and intentionally fulfilled.
The unity of the Christian church is grounded in the saving work of Christ and the unity of the church presupposes a multiplicity of churches. Anglicanism is an example of a family of churches committed to the main points of faith while allowing a considerable degree of freedom. The church is set apart from the world in order to bear witness to the grace and salvation of God. This is a theological and not moral understanding of holiness. The local church represents the wider, universal church.
