Fifty years after the death of Rev. Dr. Martin Luther King, Jr., Catholics can still learn much from his legacy, said a leader in the largest predominantly black Catholic organization in the U.S.

"Dr. King's legacy is one of faith and overcoming external forces working against you. His life, work, and ultimate sacrifice illustrate that we are called to work for the greater good," Percy Marchand, associate director of the Knights of Peter Claver, told CNA April 3. "Dr. King's legacy is a shining example of self-deprecation and personal sacrifice for one's fellow man."

"Dr. King would not want us to look upon this day in sadness," Marchand continued. "He would want us to look at it with inspiration and rededication; with hope and commitment; with love and compassion – even for our enemies or those who don't love us."

The Knights of Peter Claver is a New Orleans-based Catholic fraternal order present in about 39 states and in South America. Its membership is significantly African-American but open to all practicing Catholics without regard to race or ethnicity. Many of its members played a role in the U.S. civil rights movement of the mid-20th century, in which King, a Baptist minister, was the most prominent leader.

On Wednesday, the order joined in observing the 50th anniversary of the 1968 assassination of King in Memphis, Tenn. Catholic Bishop of Memphis Martin D. Holley led celebrations of two Masses and a "Walk of Faith" from a Catholic church to the National Civil Rights Museum in time for a program and a moment of silence.

Knights of Peter Claver Supreme Knight James Ellis and executive director Grant Jones were among those in attendance at the Memphis events.

"Dr. King was just a young man when he accepted the challenge that would ultimately lead him to being one of the most influential and powerful leaders in our history," Marchand told CNA. "He wasn't a millionaire. He wasn't famous. He hadn't 'made it.' We must each look at our lives and ask what we are doing to lead, to serve, to positively impact the world in which we live."

"Our Catholic faith is rooted in humanity and teaches us that we were created in the image and likeness of God," he continued. "Therefore, we have no room for promotion or tolerance of racism."

While many Catholics were involved in the civil rights movement from the start, "there were many more who were actively fighting against civil rights and still more who stood silent," Marchand noted, stressing that Catholics must be "strong in our faith" and must live out Catholic social teaching.

"We must directly face the evils that tend to divide us or negatively impact others," he said. "This is what our Teacher, Jesus Christ, illustrated through His own life."

"Dr. King taught us to be principled and genuine in our faith and actions. He taught us not to lower ourselves or compromise our values. He taught us to have faith and be obedient to our Heavenly Father rather than dwell on worldly problems," said Marchand, adding that King "allowed God to lead his path and ultimately, his message prevailed."

Marchand suggested many Catholics needs to improve their efforts to truly understand diversity and inclusion.

"The Church must be bold and purpose-driven when it comes to standing up for what is right and just – for all people," he said.

Historically, some in the Catholic Church failed to stand up against segregation and racism, Marchand said.

"While the Church has certainly become more diverse in the years since the civil rights movement, Catholics in the South who had known slavery and segregation as a way of life, looked at those systemic issues as natural."

As Church leaders started to take a stronger stance in rejecting segregation, Catholics were called by their faith to "turn away from hate and divisiveness," he said, and the Church allowed many Catholics to "come together and begin the process of healing."

In Marchand's view, race relations within the Church have significantly improved since King's day.

"In culturally diverse parishes across the country social interactions in various ministries have provided opportunities for all Catholics to learn and understand each other better," he said. "Divisions remain in the Church to this day. We still have what are considered 'White parishes' and 'Black parishes' but the differences tend to be more about worship style and comfort rather than exclusion and hate."

The Knights of Peter Claver were founded in Mobile, Ala. in 1909 by four priests and three Catholic laymen to serve African-Americans and other racial minorities. Its founders were concerned the Catholic Church would lose black Catholics to fraternal and secular organizations, at a time when racism in some parts of the South sometimes curtailed participation in parish life and Catholic associations.

In their opposition to segregation, the Knights of Peter Claver worked with the National Association for the Advancement of Colored People and the National Urban League. One of its leading officers, civil rights attorney A.P. Tureaud, worked with future Supreme Court Justice Thurgood Marshall to help overturn segregation laws. The order's New Orleans headquarters hosted early meetings that led to the launch of the civil rights movement.

The order has six divisions, including the Ladies of Peter Claver and two separate junior divisions for young men and young women.

A Knights of Peter Claver spokesman told CNA that many local units of the organization would hold their own commemorations of King.
