Today I was preparing my Corpus Christi homily and included details of the Eucharistic Miracle of Bolsena/Orvieto as evidence for the truth of our Faith that Jesus is really present in the Eucharist. This was the miracle that prompted Pope Urban IV to institute this feastday back in 1264. See this link: http://www.therealpresence.org/eucharst/mir/bolsena.html
Another miracle – but perhaps more like an “anti-miracle” – is the fact that over 50 million preborn babies are killed by abortion annually and it is a complete non-event. This is almost as true inside the Church as well as outside the Church.
Here is a related recent pronouncement of Pope Francis.
