Then at Café Lingo, he learns about an English language teaching enterprise led by a methodist church to help new arrivals to the island, with an ethos inspired by the Bible's stories of welcome.Back at the cathedral, Aled meets some of the volunteers who tend to the gardens and hears how faith influences their work and what made them to want to help.
