Jesus said that baptism is key to being saved.
He did not say that baptism into a religion was necessary, just in the name of the father, son, holy spirit.
Therefore ANY baptism using the method laid down by Jesus is enough to meet the requirement Jesus spoke of.
Next time you attend an assembly or convention, look at the ages of those being baptised as Metatron says, this will tell you where the Soc is focussing its efforts today.
