Good gravy!

This is exactly what I mean by straw men.

There is no doubt that Christ is present where two or three are gathered.  This is due to the Priesthood of the Baptized.  This presence, however is distinct from other ways that Christ is present in the Church.  

The Sacraments are specific points of encounter with the ministry of Christ.  They put us into touch with one or more aspects of his ministry--in a concrete manner.  The Ministerial Priesthood is how God mediates the graces of the Sacraments to the people of God.  While Christ is present where two or three are gathered, the presence in the Sacraments is a specific type of presence that mediates specific types of graces.  

While we do not absolutely need the Sacraments to experience the presence of Christ, God desires to grant specific graces though the Sacraments.  We miss out on a more fuller and perfect encounter with Christ if we dismiss the Sacraments as superfluous.
