Conversion

Hi all, 

I'm often  amazed at how easy it is to become a Christian :when at uni I was asked  to try an alpha course in two months and that's it, people were  converted . It seemed to me to be based on a type of emotional  reaction  , a sort of temporary mass hysteria. I do NOT mean to be disrespectful in that regard, but I honestly cannot understand how those people made such a (presumably ) life changing  decision in such a short space of time. More importantly would these people maintain their new found faith and how did they know enough to stick with it?

 You see by  contrast in my own faith of Judaism we don't actively look for converts or bums on seats . A  potential convert was traditionally discouraged  three times to make sure they were genuine.

  A convert has to:

1). Undertake a Bris (if male ). If already circumcised prior to conversion a token prick of blood is taken.

2). Be immersed in a mikvah

3). Say that they will adhere to the Mitzvot

The process involves :

1). Being initially sponsored by a Rabbi

2) An initial appraisal by the Beth Din (judicial court) that the candidate can begin training to convert.

3) . Staying with a Jewish family so that question convert can see Judaism in day to day living.

4)intensive study and tutoring  such as:

Learning Hebrew

Understanding Judaism e.g. Shabbat , holidays,  Jewish Synagogue services, basic Jewish law 

5) Finally after all of that a candidate has to go before a Beth Din (religious court) to be interviewed by dayanim (religious judges , extremely learned  Rabbis) and to meet with their approval that the candidate is sincere and meets the criteria for conversion according to Jewish law. Only then and with all the criteria met  will they approve the convert and  issue a certificate of conversion , in which case  the person be considered Jewish. There are also clearly financial costs  to consider of this process.

My question is :

 which system is "better"? The quick approach in which (presumably you learn the basics after conversion) or the Jewish approach of knowing what is expected of you from the off, but which takes much longer ?
