From His Hermeneuticalness, Fr. Finigan:
The Catholic Herald is floating the idea of holding a March for Life in London. This is an excellent idea: we wouldn’t be able to match the scale of the US March but we could certainly make an impact. It would also be an important opportunity for the Catholic Church to witness to the value of human life as well as co-operating with those other Christians and people of other faiths who share our convictions on this issue.
The article recognises the possible problems but I agree that these could be overcome by marshalling some of our energetic and enthusiastic young pro-lifers. See: Let’s take courage and hold a March for Life in Britain.
For an idea of what happens in the USA, see the official March for Life website and many US blogs which cover it. You do need to look at the blogs to find out much about it. As the Herald said:
If you rely on the television or daily papers for your news this is probably the first you’ve heard of it. Even in the United States it barely registered in the mainstream media.Fr John Boyle was there and has posted a slideshow of photos from the march. It also worth looking at his advance information from a couple of weeks ago.
