Jesus Christ made visible the invisible God as we read in John 1:1–2. In him we experienced God's life-giving love. That is why Christ commanded his disciples to love one another as he loved them — so that all would know they were his disciples as we read in John 13:34–35. In this way Christ's disciples make visible the Risen Christ who is no longer present to us as he once was when he walked and talked with the people of his day.
The sacraments of the church community — baptism, confirmation, Eucharist, penance, anointing of the sick, marriage and holy orders — make visible and effective, through word and action, the Risen Christ's life giving presence.
Sometimes the sacraments are thought of as falling into groups. The sacraments of initiation are those milestones that help draw a person closer into relationship with Jesus Christ and the church community. Baptism and confirmation are two very clear examples of this though Eucharist is also included. However, it is unique in that it is a recurring sacrament that continues to sustain us throughout our faith journey.
The sacraments of healing include anointing of the sick and reconciliation. In the anointing of the sick, we pray for God's healing of mind, body and soul. In reconciliation, we find God's unconditional forgiveness. Therefore we confess our sins with the desire to renew our commitment to living in Christ and demonstrate our renewed commitment through penance.
The sacraments of marriage and holy orders are sacraments of vocation. Both are responses to God's call to lifetime commitments.
