Christianity has one way into heaven, baptism, but beyond that things diverge quickly. It's better (IMO) than believing different religions but acting the same in practice. As Chesterton put it:
"So in Christendom apparent accidents balanced. Becket wore a hair shirt under his gold and crimson, and there is much to be said for the combination; for Becket got the benefit of the hair shirt while the people in the street got the benefit of the crimson and gold. It is at least better than the manner of the modern millionaire, who has the black and the drab outwardly for others, and the gold next his heart. But the balance was not always in one man's body as in Becket's; the balance was often distributed over the whole body of Christendom. Because a man prayed and fasted on the Northern snows, flowers could be flung at his festival in the Southern cities; and because fanatics drank water on the sands of Syria, men could still drink cider in the orchards of England. This is what makes Christendom at once so much more perplexing and so much more interesting than the Pagan empire; just as Amiens Cathedral is not better but more interesting than the Parthenon. "
