Being an American monarchist who believes his own country’s Revolution was unjustified and winces when people quote the Declaration of Independence, I think I’m safe from any accusations of putting nation in place of God when I say that I like having nationally themed hymns on occasion.
There are few songs in the hymnal that I dislike, this happens to be one of the them. It’s like drinking warm water. It’s innoucous enough, I love my country but yours is OK to.
The melody to be is like fingernails on a chalkboard.
That set of words are kind of silly, yes, but the “Finlandia” tune itself is beautiful.
I remember once attending a Rememberance Day Mass (11th Nov or the nearest Sunday here in the UK) and the entrance hymn was “I vow to thee my country”. It struck me as the Catholic Church trying too hard to show its’ patriotic credentials, as I had attended Church of England services for 6 years prior to my conversion, and had never heard this hymn sung, despite the C of E being the ‘established’ National church. I’m still uncomfortable with the lyrics (“I vow to thee my country, all earthly things above/ entire and whole and perfect the service of my love/ the love that asks no questions

the love that stands the test…”)
I don’t see reason to be uncomfortable about it, especially if you notice the last verse:
*
And there’s another country, I’ve heard of long ago,
Most dear to them that love her, most great to them that know;
We may not count her armies, we may not see her King;
Her fortress is a faithful heart, her pride is suffering;
And soul by soul and silently her shining bounds increase,
And her ways are ways of gentleness, and all her paths are peace. *
Our country may be “above all earthly things”, but it is without doubt below heavenly things.
