  We develop a theory for strain control of Majorana zero energy modes and
Josephson effect in black phosphorus (BP) devices proximity coupled to a
superconductor. Employing realistic values for the band parameters subject to
strain, we show that the strain closes the intrinsic band gap of BP, however
the proximity effect from the superconductor reopens it and creates Dirac and
Weyl nodes. Our results illustrate that Majorana zero energy flat bands connect
the nodes within the band-inverted regime in which their associated density of
states is localized at the edges of the device. In a ferromagnetically mediated
Josephson configuration, the exchange field induces super-harmonics into the
supercurrent phase relation in addition to a {\phi}0 phase shift, corresponding
to a spontaneous supercurrent, and strain offers an efficient tool to control
these phenomena. We analyze the experimental implications of our findings, and
show that they can pave the way for creating a rich platform for studying
two-dimensional Dirac and Weyl superconductivity.
