A historic Hawker Hunter fighter jet, taking part in the show, came down on the A27 Saturday afternoon, hitting several cars.
At least 7 people died in the accident.
Three of the victims have been named as Worthing United footballers Matthew Grimstone and Jacob Schilt, and personal trainer Matt Jones.
The family of Matthew Grimstone have paid tribute to their 23-year-old son saying: "He was the kindest person you could ever meet, with a great wit."
The Diocese of Chichester said St Mary's de Haura Church in Shoreham will hold a special silence before their Sunday service and candles would be lit in the church's St George's Chapel afterwards.
St Mary's and the Church of the Good Shepherd on Shoreham Beach will remain open all day to anyone who wants to pray.
