Epigram 4: How weakely is that weake Religion grounded

How weakely is that weake Religion grounded,
That thinks the Church on Peters corps is sounded?
The spouse of Christ is built on faiths firme rocke,
Which not the fury of hells direfull shock,
Though all the fiends in troopes doe her assaile,
Yet gainst Gods power their force cannot preuaile.
Peters confessing Christ Gods true begotten,
Is sure the Churches ground, but Peter's rotten.
Or else if Peter neuer had had life,
Through want of him Christ neuer had had wife.
For tis an Article of faith profound,
To know St. Peter for the Churches ground.
And who denies it shall haue fire and rope,
Beleeue me Reader or goe aske the Pope.
But yet I muse in what place of this earth,
Gods Church did stand before Saint Peters birth?
