Much of The Catholic Herald’s content – news, features, comment, letters and reviews – is not available online. This week, Bishop Mark Davies of Shrewsbury reviews the Pope's masterly new book; Fr Ashley Beck argues that Church teaching can help doctors make hard decisions about costs; Damian Arnold meets Robert Colquhoun, the 28-year-old leading a thriving pro-life campaign in London; and Edmund Matyjaszek says that Walsingham is becoming a focus of Christian unity 950 years after Our Lady appeared there in a vision. Fr John Zuhlsdorf, meanwhile, explains one of the most striking changes in the new Mass translation, "And with your spirit".
