Here is John Calvin on the glory of a Christain marriage. He notes the support, help, companionship, assistance, harmony, friendship and peace that God has wrought in providing marriage for man and woman:
Now, since God assigns the woman as a help to the man, he not only prescribes to wives the rule of their vocation to instruct them in their duty, but he also pronounces that marriage will really prove to men the best support of life. We may therefore conclude, that the order of nature implies that the woman should be the helper of the man. The vulgar proverb, indeed, is, that she is a necessary evil; but the voice of God is rather to be heard, which declares that woman is given as a companion and an associate to the man, to assist him to live well. I confess, indeed, that in this corrupt state of mankind, the blessing of God, which is here described, is neither perceived nor flourishes; but the cause of the evil must be considered, namely, that the order of nature, which God had appointed, has been inverted by us. For if the integrity of man had remained to this day such as it was from the beginning, that divine institution would be clearly discerned, and the sweetest harmony would reign in marriage; because the husband would look up with reverence to God; the woman in this would be a faithful assistant to him; and both, with one consent, would cultivate a holy, as well as friendly and peaceful intercourse.
