Indeed the primordial mission of the Church is to proclaim God and to be his witnesses before the world.  This involves making known the true face of God and his loving plan of salvation for man, as it has been revealed in Jesus Christ.  To prepare such witnesses, it is necessary for the Church to develop a profoundly religious catechesis, nourished on the Gospel, which will deepen man’s encounter with God and forge a bond of permanent communion with Him.
