What physical act do you feel called to perform when you stand in the presence of God on Holy Ground?
Moses removed his sandals. Every man used to take their hat off. When receiving communion Catholics used to kneel. What do you do?
I make the sign of the cross. I will genuflect or kneel if canonically appropriate and liturgically appropriate for the church I am in.
The Coptic Orthodox and Ethiopian Orthodox and many Syriac Orthodox retain the ancient tradition of removing their shoes during worship - the clergy wear liturgical slippers. The Armenians do not do this, probably because of the much colder temparature. All of my visits to Oriental Orthodox churches however have been to Coptic and Syriac Orthodox churches, and in the Coptic ones, everyone removes their shoes, myself included, and I quite like it.
In Coptic Orthodox worship, as my friend
@dzheremi can attest, there is a beautiful sense of unity and Christian love. The services are long, longer than those of most other Orthodox churches (only the Ethiopian Orthodox have services which are definitely longer), but they are beautiful, and never boring. When visiting a Coptic parish I like to get there at the very start of things, which is usually 8 AM, knowing that the liturgy will probably end at around 11:30 followed by a parish lunch, so I will be there until at least 1 PM.
The Copts also bake the bread both for consecration in the Eucharist, and the
antidoron, the blessed bread for distribution to everyone, fresh, on the morning of the service, and this smell combined with the smell of incense in a Coptic parish I find to be quite heavenly.
In many Eastern Orthodox churches the bread that will be used is presented the night before in a liturgical service known as the
Litia, which is also very beautiful but unfortunately we don’t get to smell it baking.
