I came across this at the conclusion of Bishop Vigneron's address to the US Bishops on the new translation of the Missal. I had never heard this quote from Pope John Paul II, but I find it a beautiful image:
"The time has come to renew that spirit which inspired the Church at the moment when the Constitution on the Sacred Liturgy was prepared, discussed, voted upon and promulgated, and when the first steps were taken to apply it. The seed was sown; it has known the rigors of winter, but the seed has sprouted, and become a tree. It is a matter of the organic growth of a tree becoming ever stronger the deeper it sinks its roots into the soil of tradition."
