The Eucharist is between Jesus and the person.  The community is incidental.  2000 years of Sacred Tradition formed by countless saints, martyrs, priests and devout laity, all guided by the Holy Spirit, have affirmed and deepened our understanding that a person needs to be in a state of grace achieved by His gift of confession in order to show our love and loyalty to Jesus who gave His own life to save each of us from our broken nature created by original sin, to show us the way to eternal life with Him. 

  Again what kind of love of God is it that a person can't even be bothered to at least try to be in a state of grace before receiving the real presence of Jesus in the Eucharist.

If you can't even love God in the simplest things then can you really love anybody else but yourself, if that.
