Caro Pedro e cari Tutti, anche e soprattutto il Natale, è una lieta novella, un'INFORMAZIONE bella e buona. Difatti Gesù Cristo ha preso la "forma" di carne dell'uomo, senza perdere quella divina. Per tutti, credenti e non credenti o ritenuti tali. D'altra parte, se Dio esiste, come esiste, esiste per tutti, che noi lo vogliamo o meno. Quindi colgo l'occasione per rivolgerVi un AUGURIO di A.more, U.ni-versale, G.rande, U.nico, R.adioso,I.nter-nazionale,O.nto-logico. Un abbraccio da estendere alle Vostre famiglie. Francesco Rizzo.
