what is the tension that followed after Jaja didnt receive communion

When the family arrives home from church, Papa demands an explanation from his son. Why did he not receive communion? Jaja says it is because the wafer gives him bad breath. Papa is shocked and reminds Jaja that not accepting the Host – the body of their Lord – is death. Jaja responds that he will die. Papa then throws his heavy leather-bound missal across the room, missing Jaja but breaking his wife’s beloved figurines.
