The 'Mercy Bus' is the idea of Friends of Divine Mercy Scotland
Bishop John Keenan of Paisley celebrated Mass on a bus on Saturday in what was described as the first celebration of its kind in Britain.
The “Mercy Bus” had been on a week-long tour of central Scotland.
Volunteers handed out cake and tea and priests heard Confessions on the top deck.
The initiative was the idea of Friends of Divine Mercy Scotland.
