One of the most common mistakes I've heard made by my fellow Christians is the idea that the highest aspiration of a "Christian society" is that it be a just society, that is, one which proclaims "justice for all." We therefore have such things as the "social justice" movement which mistakenly believes that it is there to promote justice, and nothing more, or pro-life groups which would be more properly classified as anti-abortion groups, or Christian groups whose interest is in protecting this or that set of rights. In point of fact, even the pre-Christian pagans recognized justice as a virtue: along with prudence, temperance, and fortitude it became one of the cardinal virtues. Therefore, the "just" society is a society which even pagans ought to--and sometimes did--strive to achieve. Thus, by all means we as Christians are called to work for a more just society--one in which to each is given his due, and all rights are recognized--and this may be the best society on the level of government and social institutions.
