What do people mean by salvation?
What do people see as being promised, or quaranteed, or secured; in, or as salvation?
Could differing emphases on baptism, reflect differing emphases on, and understandings of salvation?
I put forward these questions as someone for whom salvation remains something of an alien idea: and certainly does not figure experientially, in how I am, experience faith and trinity, proffess or witness.
It often seems to me that salvation: the idea and the pursuit of it; is a stumbling block, on the faith path.
It seems to me that the current Christian crises, are crucially being driven, if I can be forgiven the colour of the epithet, by salvation junkies.
Water baptism, as a ritual of formal induction to an in-group, as opposed to some personal experience of God encounter: may well be a crucial component part of what is driving these crises; where Christianity can become simply an in-group ideology, with being "spirit filled", and essentially within congregation, displacing origonal encounter with God, and alone.
Removing water baptism as formal ritual: might then become an integral aspect of retrieving the trinity truth from in-group explotation and domination; as preparatory step in encouraging Christians to again approach God alone.
It might all depend on how problematic we deem prevailing congregationalism to have become, in this regard.
