Papal Motto reveals the way forward

Diversity not based on unity is anarchy. Unity not based on diversity is tyranny - Blaise Pascal

E pluribus unum – Out of many, one – is a traditional motto of the United States,

In varietate concordia- harmony in diversity- the official Latin motto of the EU

Anima una et cor unum in Deum - One mind and one heart intent upon God Latin motto of the Order of Saint Augustine

In Illo uno unum

The Episcopal motto of Pope Leo XIV is “In Illo uno unum”, words pronounced by Saint Augustine in a sermon on Psalm 127 to explain that “although we Christians are many, in the one Christ we are one".

 St. Augustine, Enarratio in Ps. 127, n. 3, in ML. 37, 1679: 

“Multi homines sunt, et unus homo est... Unus ergo Christus, caput et corpus. Et multi homines sunt, et unus homo est; multi enim Christiani, et unus Christus. Ipsi Christiani cum capite suo, quod ascendit in caelum, unus est Christus; non ille unus et nos multi, sed et nos multi in illo uno unum. Unus ergo homo Christus, caput et corpus.” — 

But also in two other places

Enarratio in Ps. 88, Sermo I, n. 7, in ML. 37, 1124:

 “Ille unicus, nos multi; ille unus, nos in illo unum; ille natus, nos adoptati.” 

Enarratio in Ps. 122, Sermo ad plebem, n. 5, in ML. 37, 1634: 

“Iam ergo in nomine Domini redempti sanguine ipsius, loti lavacro yo filii simus, filius sumus; quia sic multi sumus, ut in illo unus simus.”
