Born in a small town near Oudenaarde, Lambrecht was educated in the local school.
After his studies in St. Joseph Minor Seminary and the Major Seminary of Ghent, he became Doctor of Sacred Theology at the Catholic University of Leuven, where he also taught.
He was appointed to a canonry of St Bavo's Cathedral, Ghent, and served as Vicar General in 1880–1886, when he became coadjutor bishop to Henricus Franciscus Bracq.
Lambrecht became bishop elect after Bracq's death, and was consecrated by Pierre-Lambert Goossens.
He became ill during episcopal visit, and was buried in his birthplace Welden.
