Baloney! Do you imagine poor God can’t do anything without your friends in Rome?
Tell me, TC, did the “gospel” exist BEFORE there was the Roman Catholic church?
God can, of course, do anything that He wants to do. In this case, however, He chose to use the Catholic church as His messenger. The Holy spirit inspired the early Catholics and thus they became His servants. They are no more special than anyone else, just happen to be His chosen group for that task.
As for your second question, there were no gospels, as such, before there were catholics. St Peter and the rest of the Apostles became known as Catholic and it was that group that wrote, transcribed, copied, edited, etc etc etc what we know as new testament scripture. Before the Apostles there were no Gospels and the Apostles were the first Catholics...
