Thanks for the suggestion. When I typeset in latex the following

\documentclass{amsart}
\usepackage{verbatim}
\newcommand{\bp}{\begin{proof}}
\newcommand{\ep}{\end{proof}}
%\renewcommand{\bp}{\begin{comment}}
%\renewcommand{\ep}{\end{comment}}
\begin{document}
\bp
0=1
\ep
help
\end{document}

it works fine, but when I typeset in latex

\documentclass{amsart}
\usepackage{verbatim}
\newcommand{\bp}{\begin{proof}}
\newcommand{\ep}{\end{proof}}
\renewcommand{\bp}{\begin{comment}}
\renewcommand{\ep}{\end{comment}}
\begin{document}
\bp
0=1
\ep
help
\end{document}

it doesn't. I get in the test console the message

[snip]

(/usr/local/texlive/2008/texmf-dist/tex/latex/amsfons/umsb.fd))
Runaway argument?
! File ended while scanning use of \next.
<inserted text>
\par
<*> test.tex

?

I get a similar error message when I try just

\documentclass{amsart}
\usepackage{verbatim}
\newcommand{\bp}{\begin{comment}}
\newcommand{\ep}{\end{comment}}
\begin{document}
\bp
0=1
\ep
help
\end{document}

and also a similar error message when I try to define the corresponding
new environment for "proof".

Is there some problem with the relationship between the verbatim.sty
package and the ams classes? Or am I just doing something wrong?
It seems that the \begin{comment} part is okay, but the
\end{comment} part is causing the problem.
