Here are the introits for the six Sundays in Lent.
Note on the text: Laetare features an antiphon drawn from Isaiah 66:10-11. The text of the common service omits a portion of verse 11 that is retained in the gregorian, though even this is edited slightly. It seems that even in the 16th century there were simply some things you could not say in Church! As for Palmarum’s introit, the text of the common service has notable differences from the Latin (see the Douay-Rheims version for a more literal translation).
