I believe that you misunderstand arranged marriage and marriage in general. The Christian understanding of marriage has always, always been one of mutual consent. The Catholic Church, for one, does not consider marriages valid unless both husband and wife have exchanged their free consent to the marriage as it is understood. That is, they know the implications of the vows, they know marriage is a lifelong covenant between one man and one woman, and they are both willing to lovingly accept children into their family by whatever means. Therefore, Christian families arranging marriage rely on the consent of bride and groom. It may be somewhat grudging and it may not come from a place of romantic love, but free and willing consent must be granted, or that marriage is 100% invalid.
