Do you actually care? You don't seem to care about Ecclesiology.

The short answer which could be incorrect, is Divine Liturgy is when we can commune and partake in the Body and Blood of Christ. The actions imbued with the life of Christ and the Gospel are reminders and represent what Christ came to do and what we are called to do. Additionally, we want to pray and worship with all of our senses.

What do you think happens when you're saved, what is the end goal, beside heaven and eternal paradise?
