what churches does this leave for Ukrainian Christians?

The Ukrainian Catholic Church (cf. "Shoes of the Fisherman"), and all the minor Protestant/evanglical churches.

“The Ukrainian Catholic Church (cf. “Shoes of the Fisherman”), and all the minor Protestant/evanglical churches.”

Whereas in Russia,the only permitted Church is the Russian Orthodox Church. All others are banned/discouraged.
