The first exemplification of the Knights of Columbus Fourth Degree was held in New York City, on February 22, 1900. The ritual added Patriotism to the three principles of the Order: Charity, Unity and Fraternity. Any Third Degree member, in good standing, one year after the anniversary of his First Degree, is eligible for membership in the Fourth Degree.

Members of the Fourth Degree are committed to conduct themselves honorably as Christian gentlemen in their private and public lives, as well as acting patriotically for the good of their nations. 

The Fourth Degree emblem (right) is composed of the triad featuring the dove, the cross and the globe. The dove, classic symbol of the Holy Spirit and peace, is shown hovering over the orb of the Earth (globe). Both are mounted on a variation of the Crusader's cross, which was found on the tunics and capes of the Crusading Knights who battled to regain the Holy Land from the pagans. Spiritually, the sacred symbols on the emblem typify the union of the Three Divine Persons in one Godhead, the most Blessed Trinity.

Considered under a religious aspect, we have the honor and privilege of wearing on our swords and our lapels the sacred symbol of the Most Blessed Trinity. This should always remind us to live a good Christian life, and that we should never bring dishonor on the emblem we have been privileged to wear. By this, others may see our good works, through which we will glorify our Holy Religion, our Honored Order and our Beloved Country.

Likewise, the Fourth Degree sword represents the bearer's reverence for the Eucharist and the Pope, Bishops and hierarchy of the Church, and displays publicly his willingness to protect his Church and Priests.
