Precise Definition Of Second-Class Relic?

[mme_hardy]

As I understand it, a first-class relic is part of the body of a saint, or of the True Cross.
A second-class relic is something the saint touched while living (or the coffin or tomb?)
A third-class relic is something that has been touched to a first-class relic.

That's what you see on a lot of Websites. I've always wondered, though. I assume people and pets can't be second-class relics: St. Gianna Molla had at least one child still alive when St. Gianna was canonized. Am I right that second-class relics can only be inanimate objects? Are there any other restrictions?

The Second Class Relic is an item or piece of an item [b]used by the Saint while on the body [/b](clothing, Bible, Breviary, Mass vestments, and so on). Second Class Relics are considered so precious that they are rarely entrusted to individuals, but are placed in Faith Communities

Third Class Relics typically fall into 2 categories. The first category is a piece of cloth touched to a First or Second Class Relic of the Saint. The second category, in cases where there is no known existing relic of a saint, the cloth has been touched to the shrine of the saint. Generally, the Third Class Relic is a piece of cloth, but it need not be, as long as the item so touched conveys Holiness and is touched with the intent that it be a Third Class Relic. Third Class Relics may be given to individuals, and may be sold. Fourth Class Relics are virtually the same as Third Class Relics and may be sold also.

The Third Class Relics on the Medals we use are the same Third Class Relics you would purchase if you traveled to the Shrine of the Saint and purchased a Third Class Relic there. On the back of each medal you will find the small piece of cloth set in red, which is the relic itself. Around the relic is engraved “EX INDUMENTIS” Latin for touched cloth.
