Now, these five questions have put the Pope in a stalemate. If he were to answer them by denying the Tradition and the Magisterium of his predecessors, he would pass to being formally heretical, so he cannot do it.

He, therefore, chose silence because, humanly speaking, the situation can appear to have no way out.

If you have glanced at it, but thought it a bit long to read in detail, please give it another go and read it thoroughly.
