Sacraments are easily misunderstood by many.
A piece of music can carry with it a burden that is no longer simply physical vibrations beating on the eardrums. It may carry memories, it may rouse us, or bring us to tears, and even though the music is not those things, we know that through the music we encounter those things.
In the Mass we follow Christ's command to take the bread, break it and share it, calling to mind all that Christ was and is for us. Christ promised that when we did this he would be there in the midst of us.
There are two dominical sacraments (Baptism and Eucharist) and five other sacraments (Reconciliation, Confirmation, Ordination, Anointing and Marriage) that are traditionally given place in the Church.
The old line was that a sacrament was an outward and visible sign or an inward and spiritual grace. Signs of course point to things, and declare things. The sacraments, all of them point to the Kingdom of God and declare his love for us all.
We speak about the sacramental life of Christians, and that is because we engage in rite and ritual that we may be empowered to life lives pointing to the Kingdom of God and declaring the love God has for us all.
