The Chalcedon Foundation has made a number of R. J. Rushdoony’s books available online for free.
Several of them are considered classics in the annals of Christian Reconstruction.
The Foundations of Social Order is one of them. It was published in 1968.
From the preface he wrote for the third edition, Rushdoony said:
Christianity cannot be reduced to the level of a pagan mystery religion, basically concerned with life after death, and with things personal here. The foundations of social order are indeed in the here and now, but in our faith and life, in what we believe concerning things ultimate. As men have turned from the Christian gospel, they have constructed a social gospel, and as they have surrendered God’s law for antinomianism, they have supplanted God’s law-word and they have turned to man’s word, pietism, and pious gush. Church music now often celebrates man’s feelings rather than the Holy Trinity.
This is the way of decline and death, and it must give way, and present indications tell us so, to a restoration of God’s sovereignty, grace and undiluted word. The foundation of true social order can only be in the triune God and His enscripturated truth and word.
