"We Are Climbing Jacob's Ladder" is a spiritual. As a folk song originating in a repressed culture, the song's origins are lost. Some academics believe it emerged as early as 1750, and definitely no later than 1825, and was composed by American slaves taken from the area now known as Liberia. The spiritual utilizes the image of Jacob's ladder, and equates it with the body of Christ (in ways quite similar to the teachings of Catherine of Siena). The song is in the form of call and response, and although lyrics vary from place to place and over time, they generally emphasize spiritual growth, increasing one's knowledge about God, and a call to discipleship. The striving nature of this "climb" toward God is depicted as a series of tests, and draws heavily on the New Testament tradition of the Christian as warrior—in this case, overcoming the slave-owner. The traditional lyrics hold out hope that the slave can rise up and escape slavery, and the nature of the call-and-response asks both the singing respondents and the listener for greater sacrifice to reach the next level. The spiritual implies that God's promise to the Biblical patriarch Jacob will also lead the slave to freedom.
