impugned, will nevertheless adjudicate with the utmost confidence upon every polemical question; denounce, hate, pity, or pray for the conversion of all who dissent from what they have been taught; assume, as a matter beyond the faintest possibility of doubt, that the opinions they have received without enquiry must be true, and that the opinions which others have arrived at by enquiry must be false, and make it a main object of their lives to assail what they call heresy in every way in their power, except by examining the grounds on which it rests. It is probable that the great majority of voices that swell the clamour against every book which is regarded as heretical are the voices of those who would deem it criminal even to open that book, or to enter into any real, searching, and impartial investigation of the subject to which it relates. Innumerable pulpits support this tone of thought, and represent, with a fervid rhetoric well fitted to excite the nerves and imaginations of women, the deplorable condition of all who deviate from a certain type of opinions or of emotions; a blind propagandism or a secret wretchedness penetrates into countless households, poisoning the peace of families, chilling the mutual confidence of husband and wife, adding immeasurably to the difficulties which every searcher into truth has to encounter, and diffusing far and wide intellectual timidity, disingenuousness, and hypocrisy. These domestic divisions became very apparent in the period of the conversion of the Roman Empire; and a natural desire to guard intact the orthodoxy and zeal of the converts, and to prevent a continual discordance, stimulated the Fathers in their very vehement denunciations of all mixed marriages. We may also trace in these denunciations the outline of a very singular doctrine, which was afterwards suffered to fall into obscurity, but was revived in the last century in England in a curious and learned work of the nonjuror Dodwell.(767) The union of Christ and His Church had been represented as a marriage; and this image was not regarded as a mere metaphor or comparison, but as intimating a mysterious unity, which, though not susceptible of any very clear definition, was not on that account the less real. Christians were the “limbs of Christ,” and for them to join themselves in marriage with those who were not of the Christian fold was literally, it was said, a species of adultery or fornication. The intermarriage of the Israelites, the chosen seed of the ancient world, with the Gentiles, had been described in the Old Testament as an act of impurity;(768) and in the opinion of some, at least, of the Fathers, the Christian community occupied towards the unbelievers a position analogous to that which the Jews had occupied towards the Gentiles. St. Cyprian denounced the crime of those “who prostitute the limbs of Christ in marriage with the Gentiles.”(769) Tertullian described
