That is true; if there is an interpretation of the Holy Scripture that is at odds with the teaching of the Holy Church, then that interpretation is wrong and the Church can provide the correct one. That is plain logical since it is the Holy Catholic Church that, under the guidance of the Holy Ghost, produced the New Testament and canonized and explained the Old. This is why I, too, explain the Holy Scripture in the light of the Church teachings but do not engage in debates with Protestants about their theological fantasies, beyond pointing them out and occasionally making fun of them.
So please “explain the Holy Scripture” as it pertains to the assumption of Mary.
