5.B.8 Admission to and Denial of Holy Communion
1. “The discernment of cases in which the faithful who find themselves in the described condition [“who obstinately persist in manifest grave sin" in canon 915] are to be excluded from Eucharistic Communion is the responsibility of the Priest who is responsible for the community. They are to give precise instructions to the deacon or to any extraordinary minister regarding the mode of acting in concrete situations.” 
2. Since “pastoral prudence would strongly suggest the avoidance of instances of public denial of Holy Communion,”  pastors are strongly encouraged to consult the diocesan bishop regarding any situation in which the denial of Holy Communion is to be considered.
3. Other ministers of Holy Communion (i.e., deacons, acolytes, and extraordinary ministers) are not to deny Holy Communion on their own initiative and must follow the direction of the diocesan bishop or pastor.
