Saint Matthew and St. Luke never knew St. Joseph personally; they never met him or talked to him. The most likely explanation for how St. Joseph ended up in the New Testament at all is that Mary told St. Matthew and St. Luke about St. Joseph. The wife of St. Joseph is the source of information about St. Joseph in the New Testament. Mary wanted her husband to be included in the New Testament. Saint Joseph didn’t speak much, but his wife spoke for him.
