The laity is typically encouraged to foster an appreciation of their own rite, and is invited to observe that rite unless there is good reason, e.g. Latin-Rite Catholics living in an exclusively Ethiopian Rite country. This does not forbid occasional or even, for a just cause, habitual participation in the liturgy of a different autonomous Church, Western or Eastern. The obligation of assisting at the Eucharist or, for members of some Eastern Churches, at Vespers, is satisfied wherever the liturgy is celebrated in a Catholic rite.
