To the Father we assign opera naturae; to the Son, opera gratiae procuratae; to the Spirit, opera gratiae applicatae.
Besides, all these graces were, if we may use a theological expression, gratiae gratis datae, as well as gratum facientes.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "gratiae" in a variety of sentences. We hope that you will now be able to make sentences using this word.
