Explain the significance of the ecumenical council held at Nicaea, noting in particular the effect of Nicene Creed on Christian dogma and liturgy.

What will be an ideal response?

The ideal answer should include:
- The ecumenical council was called in order to codify the way Christian "dogma" and practice was to be instituted against non-accepted teachings, like those promoted by Bishop Arius of Alexandria.
- As a result, the Nicene Creed, an article of mystical faith, became a clear model of the concept of the Trinity.
- Church leaders believed that by memorizing this creed, laypeople would be able to identify deviations from the established practice.
- The Council also established the Church's liturgy, the rites prescribed for public worship, which centered on the Latin Vulgate, Jerome's translation of the Hebrew Bible and the New Testament.
