There are people who describe themselves as “religiously tone deaf”. The gift of a capacity to perceive God seems as if it is withheld from some. And indeed – our way of thinking and acting, the mentality of today’s world, the whole range of our experience is inclined to deaden our receptivity for God, to make us “tone deaf” towards him. And yet in every soul, the desire for God, the capacity to encounter him, is present, whether in a hidden way or overtly. In order to arrive at this vigilance, this awakening to what is essential, we should pray for ourselves and for others, for those who appear “tone deaf” and yet in whom there is a keen desire for God to manifest himself. […] The Lord himself is present in our midst. Lord, open the eyes of our hearts, so that we may become vigilant and clear-sighted, in this way bringing you close to others as well!
Benedict XVI, Christmas Eve Homily, 2009.
