Citations as published in the USCCB liturgical calendar.

In US parishes the readings are proclaimed from the NABRE; the text shown here is the Catholic Public Domain Version.

Old Testament readings and the psalm are listed with a link to their chapter: the US Lectionary numbers some of their verses differently from the CPDV, so their text is not printed here. Psalm citations keep the Lectionary’s Hebrew numbering; the CPDV numbers the Psalms as the Vulgate does.
