Does the church PA have enough low end to carry the bass?
FYI from the Hartke Manual:

7. Line Out - This standard unbalanced 1/4" jack provides a line-level post-EQ and
post-Volume (and, in the B60, B90 and B120 models, post-Shape) output signal from the
B Series. You’ll usually use this to connect the B Series signal to a line-level input when
interfacing with PA systems or recording mixing consoles. The signal from this output is
the same as that from the Preamp Out on the rear panel (see #3 on page 5).
8. Headphones jack - Connect any standard stereo headphone (600 ohms or less) to
this standard 1/4" stereo jack.
When a plug is inserted into the headphone jack, the
speaker output is disconnected, allowing you to use your B Series as a practice amplifier.
The level of the signal sent to the headphones is determined by the setting of the Volume
knob—at the point where a connected speaker would clip, the headphones will clip.
WARNING: Because even the smallest B Series amplifier is capable of generating
extremely high headphone signal levels, always start with the Volume knob at
minimum and then slowly turn it up. In particular, a clicking sound is an indication
of distortion and possible damage to the headphones (and/or your hearing!); don’t
let things get to that point!
