Haymanot (Ge'ez: ሃይማኖት) is the branch of Judaism which is practiced by the Beta Israel, also known as Ethiopian Jews.
The Beta Israel lack a firm distinction between "canonical" and "non-canonical" religious texts.
Mixtures of milk and meat are not prepared or eaten but are not banned either: Haymanot interpreted the verses Exodus 23:19, Exodus 34:26 and Deuteronomy 14:21 literally "shalt not seethe a kid in its mother's milk" (like the Karaites).
Nowadays, under Rabbinic influence, mixing dairy products with meat is banned.
Beta Israel who broke these taboos were ostracized and had to undergo a purification process.
The Beta Israel of Ethiopia were the only modern Jewish group with a monastic tradition where the monks, titled as Abba, lived separated from the Jewish villages in monasteries, however, only partial groups lived as Beta Israel and wasn't practiced by the entire community, moreover it was a respected title used to honour elders.
