The world of the inquirer on the internet must be very different than the world of the baptized person, then. Funnily enough the subject of Roman Catholic sacraments has never come up in over a year of attending at a Coptic Orthodox Church. It's almost like we leave such things up to God and how He sees fit to deal with those outside of the Church, and instead focus on our own Church and its sacraments, which we do not doubt.
