It does no such thing. Christ instituted the Holy Sacraments as gifts to us.
Yep, and adding anything to that as a 'requirement for salvation' tells Him his sacrifice wasn't good enough, sorry. Question. If salvation is based on you keeping the sacraments, or your good deeds, or your observances of anything, why did Christ need to die to begin with???? Why couldn't you have just done it yourself with all of these observances?
Paul asked this same question btw and here is his answer:
I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!" Galatians 2:21
