Anyone may participate on our public discussion forum, unless the moderator decides (unilaterally) that a person has violated the standards of reasonable discussion. Prospective participants need to register a free user account before being allowed to participate on the public discussion forum.

Anyone may become an Associate Member by signing up and paying the annual fee of  US$20.  Associate members receive our newsletter and have access to our private discussion boards. They may also attend local meetings of the CSS. Associate members are not required to agree with the principles of the Society. To become an Associate member, complete the form below.

To join as an Associate member, paying $20 annually, select this option and click the “Subscribe” button at the bottom of this page. After signing up with Paypal, an administrator will contact you to set up your account.

To become a Full Member, you must

a) be a paid up Associate Member,

b) have real scientific qualifications, and

c) be a Christian in substantial agreement with the Society’s founding principles (available here.)

“Scientific qualifications” normally means at least two years of graduate education past the bachelor’s degree in medicine, engineering, math, or a natural science, and at least five years of research experience past the bachelor’s degree. The Society will consider exceptions to these standards in special cases.

Full membership costs the same as Associate membership, but full members may post papers and blog posts on this website, and may vote 1) in elections of officers, 2) on admitting new full members, 3) on bylaws changes,  4) on position papers of the Society, and 5) any awards or honors given by the Society. They may also serve on committees which draft position papers.

To join as a Full member, paying $20 annually, select this option and then click the “Subscribe” button below.

Payment via credit cards or Paypal accounts are accepted. To pay via credit card, click on the line of text that reads “No PayPal account? Pay using your credit or debit card”. The payment gateway is secure and managed by Paypal.

Those applying for full membership will also receive further instructions on what documents to send as part of their application.
