The encyclical letter Laudato Si is available here on the Vatican website. When Pope Francis discusses the Trinity, don’t think deep and inscrutable theology, but think “relationship.” Sections 238-240 come under the heading of “The Trinity and the Relationship between Creatures.” Let’s read:
238. The Father is the ultimate source of everything, the loving and self-communicating foundation of all that exists. The Son, his reflection, through whom all things were created, united himself to this earth when he was formed in the womb of Mary. The Spirit, infinite bond of love, is intimately present at the very heart of the universe, inspiring and bringing new pathways. The world was created by the three Persons acting as a single divine principle, but each one of them performed this common work in accordance with his own personal property. Consequently, “when we contemplate with wonder the universe in all its grandeur and beauty, we must praise the whole Trinity”.[John Paul II, Catechesis (2 August 2000), 4: Insegnamenti 23/2 (2000), 112]
Not three gods, but three persons, each with an aspect of being and doing among us.

Here’s an interesting difference in ordinary spirituality of Western vs Eastern Christianity: Western Christians tend to collapse the MHT into the person of the Son (with an exception for Pentecostalists) – Eastern Christians tend to be more emphatic about each of the Persons of the MHT.
For example, regarding the Pascal Triduum: the West focuses nearly exclusively on the Person of the Son, whereas the East emphasizes Trinitarian action throughout.
The Trinity is AntiChrist.
