And that's also why a Christian equivalent would have to be held at least multiple times a year, >90% of Muslims probably can't afford to go on the Hajj anyway, but since Christians are in more affluent countries, there'd be far more able to do so.
For Protestants, maybe a trip to Germany would work. 
I believe Wesleyanism has its roots in two of the three oldest Protestant denominations: that of Jan Hus and that of Peter Waldo. Taking into account the effect Wycliffe's theology affected Wesley's Anglican Church, as well as his own attachment to the teachings of Luther, it can easily be argued that Wesleyanism/Methodism is descended from all four of the earliest Protestants.
Edit: In case you were wondering, the Waldensians, numbering 45,000, have merged with the Methodists in Italy. The Moravians are down to about 245,000 members, and Wycliffe's followers no longer really exist as a church. Those that remained simply merged into the Anglican Church and, later, from the Anglican Church into the Methodist Church.
