Why is Sunday the day of rest?

[K_Choate]

Why is Sunday the day of rest in the Catholic faith, as opposed to Saturday which is the last day of the week?

I understand it to be an ordinance of the Catholic faith and not the word of the Bible. Can you point me to the exact scripture?

Faithfully,
K
