And by the Holy Spirit, He was incarnate of the Virgin Mary: and became man (Et incarnatus est de Spiritu Sancto ex Maria Virgine: et homo factus est)

ET INCARNATUS EST DE SPIRITU SANCTO EX MARIA VIRGINE: ET HOMO FACTUS EST

NARRARE

          As a recent practicing Catholic, I was incognizant of kneeling during consequential parts of the Liturgy. I would just automatically stand, sit, or kneel to synchronize myself with the rest of the faithful. This was a problem, because I was losing focus on my God. It is imperative to understand your actions throughout certain parts of the Mass to properly demonstrate humility, and veneration. Although I would get a bit frustrated, I was not too self-critical. I reminded myself, "I did not grow up as a full-fledged Catholic, much less ever heard of Latin." Learning the language was going to be a steady process. 

          Nonetheless, my studious nature prompted me to learn the phrase, "Et incarnatus est de Spiritu Sancto ex Maria Virgine: et homo factus est," from the "Nicene Creed," prayer proclaimed during Mass. Mainly, because every time these words would be pronounced, all the faithful would genuflect to almighty God. I did so too, but very suddenly. Until I learned this translated to, "And by the Holy Spirit, He was incarnate of the Virgin Mary: and became man." It was then; I genuflected to my Lord with complete admiration.  As stated in the Catechism of the Catholic Church, "... out of reverence for the mystery that made our salvation possible (paragraph #461). Following this, I provided the etymological explanation for the contextual translation, and meaning behind this pure sentence as well. 

ETYMOLOGY

• "Et" means "and" in Latin, as in English.

• "Incarnatus" is the past participle form of the Latin verb "incarnare," which means "to be made flesh" or "to be incarnated." It's derived from the prefix "in-" meaning "into" and "caro" meaning "flesh."

• "Est" is the third person singular present indicative form of the Latin verb "esse," which means "to be."

• "De" means "from" or "by" in Latin.

• "Spiritu Sancto" translates to "Holy Spirit" in English. "Spiritu" is the ablative singular form of "Spiritus," meaning "spirit," and "Sancto" is the ablative singular form of "Sanctus," meaning "holy."

• "Ex" means "from" or "out of" in Latin.

• "Maria Virgine" refers to "Mary, the Virgin." "Maria" is the ablative singular form of the name "Maria," and "Virgine" is the ablative singular form of "Virgo," meaning "virgin."

• "Homo" means "man" in Latin.

• "Factus est" is the third person singular perfect indicative form of the Latin verb "facere," which means "to make" or "to become."
