Unfortunately not biblical like the Golden Chain:

Rom. 8:29ff

“For whom He foreknew, He also predestined to become conformed to the image of His Son, that He might be the first-born among many brethren; and whom He predestined, these He also called; and whom He called these He also justified; and whom He justified, these He also glorified. What then shall we say to these things? If God is for us, so what if the Roman Catholic Organization is against us?”

The name comes from musical convention - the "Sequence" or "Sequentia" so called because it "followed" ("sequi") the Alleluia which is chanted as the deacon carries the Gospel to the ambo. One of the first musical geniuses of the Church, the monk Notker Balbulus ("the Stammerer" - who did not stammer when he sang, long before Mel Tillis) invented the Sequence as a way to memorize the complicated melisma on the last syllable of the Alleluia. These poems eventually separated from the Alleluia and were moved to stand between the Second Reading (the Epistle) and the Gospel, as the Psalm chant stands between the First (OT) and Second Reading.

The Golden Sequence is so called just because it is such a wonderful poem and melody - like the Golden Age or the Golden Rule.

If you just think of it as a hymn heralding the reading of the Gospel, it will probably bother you less.
