then, read this:

As this idolatry is primarily in the world's ideas and resulting structures, the modern day believer ought not to be concerned with the same practical application as the Corinthians. One would be hard-pressed to find a temple prostitute or even to find food offered to idols (although, if presented with either situation, it would be wise for the believer to consider their interaction with depth). Rather, the current Christian ought to relentlessly ask themselves the probing question, "what relationships, partnerships, alliances, fellowships, or portions in my life are leading me to idolatry?" As it is a continual act of cleansing, it is not something we can simply decide is always, in every case, and equal or unequal yoking. Whether it be dating an unbeliever or forming a business partnership with one, the believer must always be considering the risks of their relationships, not just with unbelievers who are not within the fold of Christianity, but with the unbelief found within their churches. Non-Christians are not the only people who pose threats to the faith and devotion of Christ for believers. In fact, the pitfalls of Christians can be even more detrimental to the morality of a believer than a non-believer. Therefore, Paul's admonition remains helpful in guiding us as we seek to be set apart in devotion and pure worship of Christ.
