The body of former heavyweight boxing champion Joe Louis will rest at the 19th Street Baptist Church Monday and Tuesday prior to burial Tuesday afternoon at Arlington National Cemetery.

A spokesman for McGuire's Funeral Home said that an open viewing is scheduled at the church, 4606 16th St. NW, from 1 until 9 p.m. Monday and from 9:30 until 11 a.m. Tuesday.

Services are scheduled at 1 p.m. Tuesday at the Memorial Chapel at Fort Myer. No formal processional to Arlington was scheduled as of late yesterday, but those plans may change, according to the McGuire spokesman.

The body of Mr. Louis, who died last Sunday of a heart attack, is scheduled to be flown here today. President Reagan wavied regulations that would have prevented Mr. Louis burial at Arlington.

Mr. Louis' professional career spanned 17 years and 71 fights, of which he won 68. He captured the heavyweight crown in 1937 and held it for 12 years, longer than any other man. He defened the title a record 25 times.

His most-remembered fight occurred in 1938 when he knocked out Germany's Max Schmeling in one round in New York. As the Rev. Jesse Jackson eulogized Mr. Louis on Friday in Las Vegas: ". . . What was at stake on the ego of a nation and the esteem of a race of people. In a way that politicans and potentates couldn't go. Joe made the lion to lay down with the lamb."
