Regarding the "machina triplex", I found a seemingly relevant passage: "When explaining the second petition of the Lord’s Prayer, Bellarmine closely follows the Tridentine Catechism and reproduces its threefold understanding of God’s kingdom." (https://www.academia.edu/37770869/The_Natural_Kingdom_of_God_in_Hobbess_Political_Thought_History_of_European_Ideas_) You might want to check the source: Robert Bellarmine, De bonis operibus in particulari, in Ven. Cardinalis Roberti Bellarmini Politiani S.J. Opera omnia (hereafter Opera omnia), vol. 6, ed. Justinus Fèvre (Paris: Vivès, 1873).
