I'd like to hear more about the ESSENTIAL part.
Jesus himself submitted to Baptism, and He also instituted Communion. These I consider essential in the life of a Christian. This is not to downplay the importance of the other sacraments, but they are not essential (i.e., one does not have to enter into marriage, but this does not diminish the power of this and the other sacraments).
This is all I meant - not trying to stir up a problem for anyone.
Thanks,
These are the only two of the seven sacraments which Jesus himself took part in. The others are important, but we can lead a holy life without them. But these two are spelled out in scripture as part of holy life in Jesus.
