Key characteristics shared across Eastern Catholic churches include: the Divine Liturgy (rather than the Latin Mass) as the primary worship form, married men permitted to receive ordination to the priesthood (though bishops are celibate), a strong apophatic theology (emphasizing what cannot be said about God), and the Eastern theological concept of theosis — salvation as participation in the divine life. Each Eastern Catholic church has its own liturgical language and heritage.

In the United States, the most common Eastern Catholic communities include the Melkite Greek Catholic Church, the Maronite Church, the Ukrainian Greek Catholic Church, Byzantine Catholic (Ruthenian) churches, and the Chaldean Catholic Church.
