I want to know the answer to the following question:
What term did Irenaeus use to describe the Christian community's ideologies?
All the background I'm provided with is that "He described the community's beliefs and doctrines as orthodox (from ὀρθός, orthos "straight" + δόξα, doxa "belief") and the Gnostics' teachings as heretical.[citation needed]". Is that enough to answer the question?
Answer: yes
