The Holy Father on lay evangelizers

"Through the testimony of their Christian life, they can carry to all sectors of society the light of Christ's message, attracting to the ecclesial community those whose faith has been weakened....Therefore, the lay faithful need to intensify their relationship with God and acquire a solid formation, especially in regard to the social doctrine of the Church....Thus, as leaven in the dough, they will be able to fulfill their mission to transform society according to the will of God."

~Pope Benedict to the bishops of Honduras
