Study history for yourself. Mayflower Compact (1620)

 IT WAS A SLIGHTLY chilly april day in the year 1607 when
three tiny boats, scarcely bigger than twenty-first-century cabin
cruisers, appeared on the horizon of the Atlantic Ocean and sailed
toward the coastline of North America, where they dropped anchor
in deep water just offshore. One hundred twenty bone-weary English
travelers then took their turns climbing down into long boats that
deposited them onto the sandy beach.
After an agonizingly long journey during which the travelers
had been packed into their tiny vessels, they were intoxicated with
the feel of land under their feet and the scent of woods and flowers.
They scrambled up the adjoining sand dunes in search of wild
berries, fresh water, and firewood. The next three days were spent
in exploration and profuse apologies to one another for the contemptible
attitudes many had displayed during their most trying
voyage. But they had come to settle a continent, not to beachcomb
on this point of land they named Cape Henry, after Henry, the son
of King James I of England.
On April 29, 1607, their spiritual leader, Reverend Robert Hunt,

Founding a Christian Nation
We, . . . Having undertaken for the Glory of God, and Advancement of the
Christian Faith, and the Honor of our King and Country, a voyage to plant the first colony in the northern parts of Virginia; do . . . solemnly and mutually in the Presence of God and one another, covenant and combine ourselves together into a civil Body Politick . . .
—Mayflower Compact (1620)

suggested they memorialize their landing in this New World. He directed
that the seven-foot oak cross they had brought from England
be carried from one of the ships and planted firmly in the sand of
what years later became the city of Virginia Beach, Virginia. These
brave pioneer men and women then knelt in prayer around the
rough-hewn cross and claimed this new land for the glory of God
and His Son, Jesus Christ.

Centuries later, in the 1930s, an official monument was erected
at this site (although, regrettably, it is no longer there) with a stone
cross and the following inscription:
Act One, Scene One of the unfolding drama that became
the United States of America.
Having begun this new land with a prayer meeting, these first
permanent English settlers to America reboarded their boats and
sailed up a large river that they named the James. In a protected
harbor on the northeast bank some fifteen miles upstream, they
founded a settlement called Jamestown, so named in honor of their
king, James of England.

The central and largest building constructed for the tiny settlement
was a church where all of the settlers worshiped God,
observed the sacraments of their Christian faith, and were taught
to obey the commandments of God. The concept of “separation of
church and state” would have been unthinkable to them because
their Christian faith and their civic government were as one. Their
concepts of life, freedom, and ordered liberty were framed principally
by the Ten Commandments of the Old Testament and the
Sermon on the Mount of the New Testament.
Without dispute, the United States of America began as a nation
of Christians and as a Christian nation framed by the commandments
of God.
