Paul says, “God’s weakness is stronger than human strength” (1 Corinthians 1:25). That awesome line gives us a key into the Mystery of Trinity. I would describe human strength as self-sufficiency or autonomy. God’s weakness I would describe as Interbeing.
Human strength admires holding on. The Mystery of the Trinity is about each One letting go into the Other. Human strength admires personal independence. God’s Mystery is total mutual dependence. We like control. God loves vulnerability. We admire needing no one. The Trinity is total intercommunion with all things and all Being. We are practiced at hiding and protecting ourselves. God seems to be in some kind of total disclosure for the sake of the other.
Our strength, we think, is in asserting and protecting our boundaries. God is into dissolving boundaries between Father, Son, and Holy Spirit, yet finding them in that very outpouring! Take the rest of your life to begin to unpackage such a total turnaround of Reality.
