His first assignment after his 1874 ordination was to the parish at St. Joseph, Kansas. It was from this base that Mollier traveled by horse to communities as distant as 120 miles. Parish histories of Delphos, Glasco, Beloit, Tipton, Osborne, Cawker City, Downs, and Norton in central Kansas cite the early services that Mollier performed in their communities before the parishes were formed.
