Ownership of your own beliefs seems more important here. A person being honest in their faith shouldn’t judged be a non-believer because they don’t rules. To me, the Algerians playing football seems the most appropriate expression of their given talents. I think the high level players of a sport participate for themselves and team mates. People who are prepared to label this as “patriotic competition” are turning loyalties of community and people into love of the abstractions of country and team.
Am I too idealistic and see the urge to excel is an act of spirituality while the act of performing for money and the false values of business we call competition is just commerce? I wouldn’t describe myself as “religious” but if I speak to god it’s my best possible self that speaks back to keep me trying to do my best.
