I got an error, saying
unable to load PKCS7 object
so I did
openssl pkcs7 -inform der -in a.p7b -out a.cer
and this helped me.

openssl pkcs7 -inform der -in a.p7b -out out.cer
return 0 exit code, but didn't work for further request.
So I did the following:
1 - openssl pkcs7 -print_certs -inform der -in a.p7c -out out.cer
2 - curl -E out.cer --key some_client_for_auth.key -X GET http://example.com

And then I get success response(200).

Thanks, but how to output to file ONLY the certificate?

I got some trailing lines in my case

subject=C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root G2

issuer=C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root G2
