a) A commission is instituted whose task it will be to collaborate with the bishops, with the departments of the Roman Curia and with the circles concerned, for the purpose of facilitating full ecclesial communion of priests, seminarians, religious communities or individuals until now linked in various ways to the society founded by Archbishop Lefebvre who may wish to remain united to the successor of Peter in the Catholic Church while preserving their spiritual and liturgical traditions in the light of the protocol signed on last May 5 by Cardinal Ratzinger and Archbishop Lefebvre.
b) This commission is composed of a cardinal-president and other members of the Roman Curia, in a number that will be deemed opportune according to circumstances.
c) Moreover, respect must everywhere by shown for the feelings of all those who are attached to the Latin liturgical tradition by a wide and generous application of the directives already issued some time ago by the Apostolic See for the use of the Roman Missal according to the typical edition of 1962.[9]
