No, they Commisarat was officially founded following the Heresey, specifically to deal with the spiritual needs of the Imperial rmy, which at the time, was having very poor morale due to the massive casualties suffered in fighting Astartes Legions. Alot of people forget, the Heresey didn't end when Horus died, it continues till this day, yet when the primarchs were still around, the fighting was intense. Especially with the loyalists being short handed (with the Salamanders, Raven Guard, and Iron Hands decimated at Istavan).
In order to hold off the traitors, the Guard was formed, and a new class of leader was needed to combat the loss of moral and corruption across the galaxy. The commisarat was created by the Lords of Terra as a buffer against the new horrors of Chaos being unleashed upon the fledgling guard.
