"Unless you eat my flesh (greek - literally gnaw) or drink my blood ( gurgle) you will not have eternal life. Does this offend you?"
So in response to Jn. 3:3, are you saying that Jn. 6:53 means that one must believe in transubstantiation and receive the Catholic Eucharist to be regenerated, and thus obtain spiritual life in himself? Remember to be consistent with your professed literal understanding.
And you are then saying that Jesus is a door.
Guess what, the Catholic church is as corrupt an organization as there is. Infiltrated with pedophiles and homosexuals and riddled with non biblical stupidity that only fools choose to believe. If you want to believe that being Catholic buys you a ticket to Heaven, feel free.
