Substituiton for grep paragraph parameter

My bash doesn't have grep -p.. I often find myself wanting to search a section of a man page for areas dealing with a specific property or parameter... For instance wanting to read everything in the man pages for bash that deal with Parameter Expansion..

Is there a way to do this with grep if you don't have the -p option?

Yes, I know awk can do it.. awk can do everything!
and yes, I know I can download a different grep binary...

I was curious of a way to do it with my grep.. for instance using regex to specify delimiters.
if not please let me know the simplest other solution..

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
