People here may or may not realise that joining the EOC is a big commitment. It's not like choosing to visit a different church every Sunday. There is a process of conversion. It's almost like joining a different religion entirely.
Conversion to the Orthodox Church from another Christian denomination, or from a non-Christian Faith or from a background of no religious practice is a very serious matter both for the Orthodox Church and for the person seeking to convert to Orthodoxy. It is, essentially, a lifetime mutual commitment.
