Ah, how wonderful! I'm glad you could understand and I'm glad it was a good experience for you.
Yes, it truly must be experienced.
It's kind of ironic to me that some who are from very different traditions will assume that "Liturgy" means "dead or passive" worship. As you said, it's very interactive and engaged. Even if we are not shouting or jumping.

(and at times we DO shout - Pascha is coming!)
Glory to God!
I do understand that it's a lot to process. I think Baptists and similar have mostly theological hurdles to overcome, though, while Pentecostals tend to have more "feel of the Liturgy" to overcome.
It's a blessing to hear someone's first impression though. It brings tears to my eyes, remembering how the sacredness of the service impacted me when I first encountered it.

Thank you.
