If you like what we do and want to regularly support our mission to build the Reign of Mary and/or assist the episcopal ministry of Bishop Athanasius Schneider, please consider becoming a Servant of Mary.
Firstly, canon law states that Catholics can participate and fulfill their Sunday obligations in any approved Catholic rite. In this case, we have the Greek Catholic Byzantine rite, the Maronite rite, the Armenian rite, and various other rites; this is a common canon law provision.
Therefore, it is clear that there is no requirement to convert, but if you wish to change from the Latin rite to an Eastern rite, you need to seek permission from Rome with valid reasons. Nevertheless, you can always attend an Eastern rite while remaining a Latin Catholic, this is allowed, and there is no necessity to change your rite.
