The phrase "the Paradise Trinity (the first triunity)" should not be taken to equate the two, since it is the members of the Paradise Trinity as individual persons who constitute the first triunity, not the indivisible Trinity itself. See 104:3.7
P112:4, 10:4.1
Of all absolute associations, the Paradise Trinity (the first triunity) is
unique as an exclusive association of personal Deity. God functions as God
only in relation to God and to those who can know God, but as absolute Deity
only in the Paradise Trinity and in relation to universe totality.
