Why do you care about the one holy apostolic Catholic Church ?
What do you lack ?
The one that calls G-d a liar? That says that the Torah is a collection of myths that formed over time and redacted constantly until it reached its final form? That says that J*sus could suspend the laws of nature but when G-d A-mighty created the universe from nothing He had to follow "natural laws" that didn't even exist? That says the church fathers were experts when commenting on "new testament" miracles but when they assumed Genesis was true they were merely "men of their time?"
How can any sane person not view such an organization with contempt regardless of how old it is or who founded it . . . especially when it falsely proclaims that its teachings are absolutely unchanged from the beginning?
What do you lack ?
I like to think I lack the chutzpah to call G-d a liar. Does that answer your question?
"One indeed is the universal Church of the faithful, outside which no one at all is saved, in which the priest himself is the sacrifice, Jesus Christ, whose body and blood are truly contained in the sacrament of the altar under the species of bread and wine; the bread (changed) into His body by the divine power of transubstantiation, and the wine into the blood, so that to accomplish the mystery of unity we ourselves receive from His (nature) what He Himself received from ours." — Pope Innocent III and Lateran Council IV (A.D. 1215)
Therefore, if anyone says that it is not by the institution of Christ the lord himself (that is to say, by divine law) that blessed Peter should have perpetual successors in the primacy over the whole Church; or that the Roman Pontiff is not the successor of blessed Peter in this primacy: let him be anathema. — Vatican 1, Ses. 4, Cp. 1
