Here's a recent hymn in Portuguese, written by a professor in Brazil. This hymn would work well for a service that involves prayer during dark times for a community. Lyrics are below:
Pelas dores deste mundo, Ó Senhor, imploramos piedade
A um só tempo geme a criação
Teus ouvidos se inclinem ao clamor, desta gente oprimida.
Apressa-te com a tua salvação!
A tua paz, bendita e irmanada co'a justiça
Abraça o mundo inteiro tem compaixão!
O teu poder sustente o testemunho do teu povo.
Teu Reino venha a nós! Kyrie eleison!
English version:
For the troubles and the sufferings of the world, God, we call upon your mercy: the whole creation’s laboring in pain!
Lend an ear to the rising cry for help from oppressed and hopeless people. Come! Hasten your salvation, healing love!
We pray for peace, the blessed peace that comes from making justice, to cover and embrace us. Have mercy, Lord!
We pray for power, the power that will sustain your people’s witness: until your kingdom comes, Kyrie eleison!
