Christian made it 7-3 with just under 5:00 left in the opening quarter when he connected on his third field goal of the year to cap a 13-play, 62-yard drive that ate up over six minutes off the clock.
Coe (4-2, 3-0 A-R-C) had a quick response at the end of the first quarter to go up 14-3 heading to the second and then forced BVU into a fumble on the the third play from scrimmage in the second quarter which led to a 48-yard touchdown strike just four plays into the drive and a 21-3 cushion.
The two teams combined for three straight turnovers on downs before Coe took over at the BVU 19-yard line with 39 seconds where it went on to tack on a five-yard rushing touchdown and take a 28-3 lead into the half.
Messerly caught his touchdown pass midway through the fourth quarter in between touchdowns by the Kohawks.
Bobby Gross chalked up a team-leading 11 tackles for the Beavers with senior Drew Volkmann right behind at 10.
Buena Vista (1-5, 0-3 A-R-C) is back on the road next Saturday to continue A-R-C play at Central College (3-3, 1-2 A-R-C). Kickoff is at 1 p.m.
