noun
evil heresies; perverse cults
A yojijukugo referring to heretical or evil religious teachings and practices, often with a strong negative moral judgment. Rare in modern everyday speech; mainly found in literary, historical, or critical contexts.
その時代、淫祠邪教は厳しく取り締まられた。
In that era, evil heresies were strictly suppressed.
邪教 is a more common term for 'heretical teaching' or 'cult', while 淫祠邪教 is a stronger, rarer four-character compound emphasizing both lewdness and heresy.
A yojijukugo combining 淫 (lewd, excessive), 祠 (shrine), 邪 (wicked), and 教 (teaching). The exact historical origin is uncertain, but it likely emerged in classical Chinese or early Japanese texts condemning unorthodox religious practices.
