Simple English Proper (Lumen Christi Gradual and Modal Responsorial Psalms). The Roman Missal gives us these Bible verses to be sung per the examples recorded: the congregation joins the cantor for the antiphon (printed), then the cantor sing the Psalm alone, then the congregation and cantor repeat the antiphon.
Propers in Latin are identical in both Ordinary and Extraordinary Form of the Roman Rite.

Responsorial (see “simple proper” above), or Gradual (cantor or schola alone)
NOTE: In the calendar year, the 15th Sunday in Ordinary Time (above) is typically on the same date as the 6th Sunday after Pentecost (below). However, The Vatican II changes in the Lectionary resulted in the antiphons above to be drawn from the 10th Sunday after Pentecost tradition.
