The Church proclaims the sanctity of life from its conception to its natural end.
There are several organisations in the UK that carry out important practical work in defence of the most vulnerable members of society, especially the unborn and the aged, three in particular are;
Life, a non-judgemental charity that offers wonderful support for mother and child both during and after pregnancy. It focuses mostly on the abortion issue. https://lifecharity.org.uk/
Right To Life which has more of a political focus, campaigning against abortion and euthanasia. http://righttolife.org.uk/
SPUC which combines both of the above approaches. https://www.spuc.org.uk/
