The chaplain's prayer is posted near the chapel of Baptist Hospital in Beaumont, Texas, a space shared by patients, families, visitors, doctors and the whole staff.

"Dear God, who makest thyself known in deeds rather than in mere words, deepen within us respect and appreciation for opportunities to serve. Thou has promised aid and blessing where men deal justly, show mercy, and serve humbly. Give us a faithfulness to our task, a patience in anxiety, added skill in work done. Add to our wills a readiness to follow thy guidance; to our hearts a compassion like unto the Great Physician who ministered in love and without favor."

The prayer was written by the Rev. Weldon Langley, the hospital's chaplain from 1960 to 1985. Langley continued part-time until 1993, completing four decades of chaplaincy work with Baptist institutions on the Texas Gulf Coast. He died in 2013 at the age of 96.

Langley's prayer has retained its strategic location as the hospital complex expanded into new, updated facilities.

"Weldon was a chaplain to the patients and their families, but he was also a pastor – year after year – to the doctors, nurses and everybody else," said the Rev. David Cross, who followed Langley at Baptist Hospital. While Langley focused on the needs of patients, "his insights into what makes life worth living made him a shepherd for everyone. He was a chaplain's chaplain."

Every year, the Global Chaplains Alliance dedicates the first Saturday of February to honoring chaplains. For me, it's impossible to discuss the ministry of chaplains without mentioning my "Uncle Weldon" Langley, who was very close to my father, the Rev. Bert Mattingly, who also had experience as a chaplain. My father died in 1999.

Chaplains work with hospitals, hospices, military units, legislatures, schools, sports teams, corporations, prisons and police and fire departments. Many, but not all, are ordained ministers. For most Americans, the chaplains they know best serve in the nation's 6,000 or more hospitals.

Pastors visit the sick and dying from their own congregations, noted Cross. For hospital chaplains, this is the heart of their work – every day.
