Nunc gaudeo in passionibus pro vobis et adimpleo,
ea quae desunt passionum Christi in carne mea pro corpore eius,
quod est ecclesia...

Now I rejoice in my sufferings for your sake,
and in my flesh I complete what is lacking in Christ's afflictions for the sake of his body,
that is, the church...

(Colossians 1:24)
