No; the phrase in Jefferson’s letter to the Danbury Baptists is “wall of separation between church and state”.
The USSR twisted that many years later, declaring in their constitution: “In the USSR, the church is separated from the state and the school from the church.”
Thank you for the clarification what’s important in my mind is that Justice Hugo Black reached for that in his 1947 Everson opinion at the Supreme Court.
That set the ball in motion for rulings on Bible Readings and School Prayer in the 1960’s and this mythology about “Separation of Church and State”.
