As a Lutheran, I can avail myself of all seven. In fact, I have availed myself of 5 - Baptism, Confirmation, Confession/Absolution, Marriage, Eucharist. That we don’t call them all sacraments doesn’t mean I can’t avail myself of them.a friend from another thread makes the typology of the 5 fishes and 2 loaves miracle.
Jesus gave his disciples 7 sacraments to feed his children spiritually, 7 sacraments that the catholic church uses 5+2 while others just avail of 2 of these.
