This post is to address proper celebration within the Orthodox church. We must understand that there is different types of celebration, and why we celebrate and how we celebrate. In Orthodoxy we do not see people screaming, jumping up and down, clapping jubilantly, or convulsing on the floor. At times I have seen people in tears, St. Pope Kyrillos is a good example of that, during the liturgy. Why is it that we say "celebrate the liturgy" if we are not jumping up and down and making our emotions known through actions? Because self control is key to sober celebration. Judgment has not come, therefore why must we be elated? Why must we yell, dance, and clap as loud as possible when we are still unsure of our salvation, in fact we are working towards it having not yet accomplished it.
We praise God for His mercy, His peace, and His sacrifice, not because we "feel good". We worship God because we love Him, not because we dont want to go to hell. In John 4:23-24 Christ teaches us about worshipping in "spirit and truth." St John Chrysostom teaches that truth being sound Orthodox worship and spirit being of the same character and "must be offered by that in us which is incorporeal, to wit, the soul, and purity of mind." He continues "For because both Samaritans and Jews were careless about the soul, but took great pains about the body, cleansing it in divers ways, it is not, He saith, by purity of body, but by that which is incorporeal in us, namely the mind, that the incorporeal One is served." (St. John Chrysostom Homilies on the Gospel of St. John)
Sober actions means a sober mind. The church has done things a specific way for 2,000 years for a reason, for our salvation. Introducing new forms of worship, or celebration, into the church leads not to sober mindedness but to chaos and a departure from the true Orthodox form of worship. Sober celebration is a spiritual celebration in the like mind of Christ and through His example and that of the apostles we know what sober celebration is.
