Bineesh Balan struck a hattrick in the first 40 minutes while Gabonese striker Henri and talented Brazilian midfielder Beto scored two goals each.
Lebanese striker Akram Moghrabi also joined the scoring party as the team registered their biggest win this season.
For Clube, diminutive Joseph Pereira scored two goals while Ogba Kalu and Japanese striker Seiya Sugishita scored the other two.
The big victory meant Churchill Brothers are now tied on points with defending champions Dempo Sports Club at the top of the table but will continue to be placed second due to their inferior head to head record with the defending champions.
Churchill Brothers coach Mariano Dias is pleased with his team's performance as they, at one stage, were a goal down despite taking a ninth minute lead through Bineesh.
Ogba Kalu scored with a stunning long ranger to bring the team on level terms before another beautiful team goal from Joseph Pereira meant Sporting Club were now ahead and that too inside the first half an hour itself.
The speedy Bineesh was in the form of his life, scoring goals almost at will. His curl from just outside the box was brilliant in the 44th minute and a minute later he completed his hat-trick. MORE
