Rev. Robert R. Malsack, Interim Senior Pastor
Bob was born in Milwaukee, WI and raised in the Upper Peninsula of Michigan (which makes him a Yooper, eh?). He attended college at Central Michigan University where he met his wife to be, Marsha, and dedicated his life to fulfilling God’s will for him. In his desire to bring health and wholeness to people’s lives, he entered college to prepare for medical school. He graduated from college with a calling to bring health and wholeness to people’s lives spiritually through service to the Church.
He attended Fuller Theological Seminary in Pasadena, CA and upon graduating he served a church in the San Joaquin Valley. After four years, he was called back to Michigan where he served a church for 27 years. Within that time period by the grace of God, the church doubled in size and became a strong witness for God in both the community and in the presbytery. During his time at this church, he served the community by coaching football and softball at the local high school. He also served on the township board. This community involvement was a strong influence on the growth of the church.
In the last few years of service to the church in Michigan, he became more involved in the work of the Committee on Ministry in the Presbytery of Lake Michigan. In so doing, God was calling him to serve as a transitional minister to churches while they were between pastors. This again fulfilled his God given passion to seek the health and wholeness of people which now would be done by serving churches in their time of transition, returning health and wholeness to the church in whatever way was most needed. He has served as a transitional minister to First Presbyterian Church of Corpus Christi, First Presbyterian Church of Sparta NJ, Community Presbyterian Church of Port Aransas TX, and most recently, New Braunfels Presbyterian Church.
People have most affirmed his strong and relevant preaching, his care for others, and his strong spiritual perspective on issues. His priority in his ministry is to know God over and above playing religion. Though religion serves as a means to know God it must never inhibit the movement of the Spirit in coming into full relationship with God the Father, God the Son, and God the Holy Spirit. One of the ways he accomplishes this is through a strong ecumenical spirit which respects all the branches on the tree of Christendom.
On a personal level, Bob and Marsha (married for 45 years) have three daughters (a realtor/dietitian living in Orange County, CA, an orthodontist living in Mt. Juliet, TN, and an educator living in Kyle, TX). They also have four grandchildren, three granddaughters in TN and one grandson in Kyle. To relax, Bob enjoys tasting craft beers and Bob and Marsha are acquiring an enjoyment of wine tasting together. Bob has also been seen on the golf course (but hopefully not watched). Bob enjoys following the professional sports teams from his roots, which makes him a Brewers fan (of no concern for you), a Bucks fan (not a threat to the Spurs…yet), and a Packers fan (hmm…this could be an issue).
Though he gave thought to retiring after his last call, the Lord made clear to him that he was not done yet, giving him a strong desire to serve St. Mark Presbyterian Church in its transition which he now looks forward to doing to the glory of God.
