This is the Divine Liturgy, which is the primary service on Sunday, and includes many prayers. This does not cover everything you will hear on a Sunday, as typically there is also Matins and specific readings based on which day of the year it is.

Happy to chat more with you via DM.
Thanks. I'll give it a read after work and DM you if I have any questions.
Sunday is the one day I can never make it to as I have two protestant churches I alternate between.
