Errors of modernism identified by beliefs that: every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true. (Papal Allocution, Maxima Quidem, 9 June 1862; Damnatio, Multiplices Inter, 10 June 1851).
Man may, in the observance of any religion whatever, find the way of eternal salvation, and arrive at eternal salvation. (Papal Encyclical, Qui Pluribus, 9 November 1846).
Moreover, it is false that the civil liberty of every form of worship, and the full power, given to all, of overtly and publicly manifesting any opinions whatsoever and thoughts, conduce more easily to corrupt the morals and minds of the people, and to propagate the pest of indifferentism. (Papal Allocution, Nunquam Fore, 15 December 1856).
