Sing joyfully to God, all the earth
Jubilate Deo. All are invited to rejoice in God the creator of all.
 A psalm of praise.  Sing joyfully to God, all the earth: serve ye the Lord with gladness. Come in before his presence with exceeding great joy.  Know ye that the Lord he is God: he made us, and not we ourselves. We are his people and the sheep of his pasture.  Go ye into his gates with praise, into his courts with hymns: and give glory to him. Praise ye his name:  For the Lord is sweet, his mercy endureth for ever, and his truth to generation and generation.

The following video analyzes the text of the document Sacrosanctum Concilium from Vatican II with respect to the music for the Liturgy of the Holy Sacrifice of the Mass.
¨Sacrosanctum Concilium on Sacred Music - a talk by Dom Cassian Folosm¨
Note how the very conservative text has been corrupted in "praxis" (without changing Church dogma) through the abuses of the post Vatican II Church by evoking the ¨spirit¨ of VII rather than adhering strictily to the texts -- exploiting even the slightest ambiguity in order to create a rupture with Catholic tradition so as to bring the Church in line with the "modern" humanist/atheistic world.
Let this be a warning with regards to the present synod. Perhaps the bishops of the Church of the early 1960s could claim that they had no idea of the consequences of the demonic forces which they unleashed upon the Church through the "pastoral" language of Vatican II.
However, with 50 years of hindsight at our disposal it is inconceivable that our bishops could be so "naive" as to "unknowingly" repeat this same mistake with respect to the Church's teachings on morality.
Woe to that shepherd that leads Christ's flock into perdition.
