April 2

In former cycles no distinct Covenant was made in writing by the Supreme Pen; no distinct personage was appointed to be the Standard differentiating falsehood from truth, so that whatever he said was to stand as truth and that which he repudiated was to be known as falsehood. At most, His Holiness Jests Christ gave only an intimation, a symbol, and that was but an indication of the solidity of Peter's faith. When he mentioned his faith, His Holiness said, 'thou art Peter’ - which means rock - 'and upon this rock will I build my church.' This was a sanction of Peter's faith; it was not indicative of his (Peter) being the expounder of the Book, but was a confirmation of Peter's faith.
