Here is a painting of St. Therese of Lisieux, an iconic image which is well-known to many.
I am privileged to own a true relic of St. Therese of Lisieux, which I wrote about in a previous post. There was no official document that went along with it, but I felt fairly certain it was the real thing. When we were out at Notre Dame recently for a football game, we visited the relic room in the back of the Basilica of the Sacred Heart, which houses a large number of holy relics--including a splinter from the True Cross and remains taken from the 12 Apostles, Pope St. Pius X, and all the saints in the Church calendar, including St. Therese of Lisieux. And my little relic (right down to the velvet-lined little glass-fronted metal reliquary, and inside, the tiny strip of paper with her name typed on it) looked exactly like the ones in the basilica's glass cases.
