I ain't a credited institute graduate
I ain't from Nazareth
My conception wasn't immaculate
I ain't master no calculus
A good addition to the rap audience

Meaning

Although Lu doesn’t have a college degree at some fancy college, isn’t a messiah from Nazareth (aka Jesus), and he isn’t very good in math, his words still hold a lot of weight and his lyricism is a good addition the modern day hip hop.

In addition, Nazareth academy is a high school in La Grange, IL near where Lupe grew up along with Immaculate Conception being a parish/grammar school in Chicago.

Lupe may have made a common mistake here, thinking the Immaculate Conception refers to Jesus being conceived while Mary was still a virgin, when it actually refers to Mary being conceived without Original Sin. Alternately, Lupe’s simply saying that he was born with sin. Take it how you will.
