From the Vatican, June 21, 2010Dear Mr. [_____]In reference to your letter of June 15, this Pontifical Commission would like to point out that the celebration of Holy Mass in the Extraordinary Form envisages the reception of Holy Communion while kneeling, as the Sacred Host is laid directly on the tongue of the communicant. There is no provision for the distribution of Holy Communion on the hand in this Form of the Holy Mass.With blessings,From the Secretariat of the Pontifical Commission "Ecclesia Dei"
