  In this paper, general rogue wave solutions in the massive Thirring (MT)
model are derived by using the Kadomtsev-Petviashvili (KP) hierarchy reduction
method and these rational solutions are presented explicitly in terms of
determinants whose matrix elements are elementary Schur polynomials. In the
reduction process, three reduction conditions including one index- and two
dimension-ones are proved to be consistent by only one constraint relation on
parameters of tau-functions of the KP-Toda hierarchy.It is found that the rogue
wave solutions in the MT model depend on two background parameters, which
influence their orientation and duration. Differing from many other coupled
integrable systems, the MT model only admits the rogue waves of bright-type,
and the higher-order rogue waves represent the superposition of fundamental
ones in which the non-reducible parameters determine the arrangement patterns
of fundamental rogue waves. Particularly, the super rogue wave at each order
can be achieved simply by setting all internal parameters to be zero, resulting
in the amplitude of the sole huge peak of order $N$ being $2N+1$ times the
background.Finally, rogue wave patterns are discussed when one of the internal
parameters is large. Similar to other integrable equations, the patterns are
shown to be associated with the root structures of the Yablonskii-Vorob'ev
polynomial hierarchy through a linear transformation.
