Special Characters in Lyrics

[Br. Samuel Springuel]

I'm trying to introduce an asterisk ("*") into a lyrics line in the 
following piece to indicate where the congregation should join in. 
However, I'm getting an error "unexpected *" when I try it.  Take the 
asterisk out and everything works fine.

\version "2.18.2"
\language "english"
<<
\new Staff \with {
        \remove "Time_signature_engraver"
}
\relative c' {
        \key f \major
        \set Score.timing = ##f
        \omit Stem
	e4  f( g ) g g-- \bar "|" g g (bflat) g g f f--( g--) \bar "|" f g 
bflat bflat( c ) bflat c d-- \bar "|" c bflat a g--( a bflat g ) g-- 
\bar "||"
}
\addlyrics {
	The ri -- sen Lord *has robed him -- self with might; let us re -- 
joice and be glad and give him glo -- ry.
        }

The only place in the documentation where I can find mention of the 
asterisk is:
http://lilypond.org/doc/v2.18/Documentation/notation/chants-psalms-and-hymns.it.html

However, this just uses the asterisk as a regular character and has it 
in a markup, rather than a lyrics line, as so doesn't seem to be applicable.

Any suggestions on what I need to be doing differently?

Also, ideally I'd like the asterisk to be centered between "Lord" and 
"has" rather than attached to "has".  Is there a way to make that happen?
