Christian is a person who adheres to Christianity.
Protestant signify people who believe in Christ but worship outside the Roman Catholic or Orthodox churches. The term is most closely tied to those groups that separated from the Roman Catholic Church in the sixteenth-century Protestant Reformation.
Doesn't matter what u call him Catholic or protestant, he believes in Christ, and that is a very good song, and he sings very well too. (but he is ugly and short... )
I studied both Catholic and Protestant bible and Hymms when
I was young in HK.
The Chinese translation of Catholic literature was done
before 1900 so it is very difficult to understand.
I like TW songs better than Cantonese songs
