Saint Basil the Great is considered very influential in the history of Christian liturgy. Although it is not clear which parts of the Divine Liturgies credited to him are actually his work, it is accepted that a vast corpus of prayers that he created has survived in different churches in Eastern Christianity.
The Nicene Creed is another common Catholic creed. This profession of faith is part of Mass and is recited at the start of Liturgy of the Eucharist and after the reading of the gospel and homily.
The Nicene Creed emphasizes many of the fundamental tenets of our faith. Its core affirmations include its statement of belief in the immortality of the soul, resurrection and forgiveness of sins through the baptismal process.
