"H" ... rubbish.
Господи, помилуй is the same in Ukrainian.
However, pronounced with an H - Hospody Pomylooy!
Х (H) for Хлiб not for (G) Господь , just as it is BoG, not BoH. and HLIB not GLIB, HLIV (хлiв) not GLIV (глiв), GLYNA not HLYNA, HVYLYA not GVYLYA.
You need to learn speak Ukrainian first....
Perhaps you need to learn Ukrainian.
There are two separate "H" sounds.
Х = хліб Khleeb with a soft "H" sound.
Г = Господь, Бог, Галина, Гадюка, гараж,...with the hard "H" sound.
Remember, Ukrainian is not Russian, nor Russian, Ukrainian.
you not excused...
1. Ukrainian Orthodox live in Ukraine , not in USA.
In USA live Americans.
2. One who you call "Ukrainians" NEVER use Ukrainian as liturgical, because each village speaks own language. "Ukraine" - is fake , just same as "Russia".
Russia 20 years old state as well as Ukraine.
before that was USSR for 70.
before that Russian Empire for about 200.
before that every city was on they own SELF GOVERNING order.
You like it or not - it is reality.
No Ukraine ever -ever -ever was in the map till now.
so in Church people pray "slavic" , home people speak any way one like to and feel comfortable, depending how much g
orilka, they drink. so and that is CHECK and MATE.
