I've been trying to say that I did not know that before Trent the church had defined as doctrine that there were seven sacraments. That previous to this there were various thoughts on the subject of the number of sacraments. Is that incorrect! 
I think most Protestant and Anglicans believe in fewer than seven. Many Protestant churches rarely have Communion, don't know if they consider it a sacrament or even if they use the word sacrament.
