Like many people I have found the images in CharlieHebdo which mock religion, and in particular Christianity, somewhat difficult and troubling. The following words of St Athanasius are, however, both a help and a comfort:
Come now, blessed one and true lover of Christ, let us, with the faith of our religion relate things concerning the Incarnation of the Word and expound his divine manifestation to us which the Jews slander and the Greeks mock, but which we ourselves venerate, so that all the more from his apparent degradation, you may have even greater and fuller piety towards him, for the more he is mocked by unbelievers by so much he provides a greater witness of his divinity, because what human beings cannot understand as impossible, these he shows to be possible (cf. Mt 19:26), and what human beings mock as unseemly, these he renders fitting by his own goodness, and what human beings through sophistry laugh at as merely human, these by his power he shows to be divine, overturning the illusion of idols by his own apparent degradation through the cross, invisibly persuading those who mock and disbelieve to recognise his divinity and his power.
Athanasius de Incarnatione Dei Verbi 1
