Someone making sacrifices outside the Sangha of Savakas, can such be expected as follower?

If people, maintaining a Buddhist identity, are good, they do whatever sacrifices of which they expect benefit or where they feel touched. Now, when a person gives outside the Savaka-Sangha, outside the Noble Ones, can he/she be called either, faith-, dhamma-follower or even Sotapanna? Would he/she be regarded as being ready and worthy to be taught by wise? *(Note, this is not given for exchange, trade, stacks or entertainment for bounds but to escape dry lands and go beyond)*
