The Rev. Albert Walker of Daytona Beach is celebrating his 103rd birthday this week. Rev. Walker was born Aug. 15, 1909. He is the founder and former pastor of Mt. Calvary Independent Freewill Holiness Church. His family says his “secret of longevity’’ is this scripture from Ephesians 6:2-3: “Honor thy father and mother; which is the first commandment with promise; That it may be well with thee, and thou mayest live long on the earth.’’ Family and friends were to celebrate with Rev. Walker on Wednesday.
