The Word does not say Trinity anywhere yet we believe the Word teaches the Trinity. Why? Because of context.
The context of the passages involving the family of Christ tell us Joseph and Mary, much to the apparent chagrin and horror of catholicism, had other children.
I know that upsets the applecart in Rome but it is very clear from the Word they did.
It may lesson Mary in the eyes of Roman Catholicism, but not anywhere else.
It never ceases to amaze that catholics will not allow the Word to interpret itself.
Context is key to understanding the Word along with the original languages.
The context of the passages involving the family of Christ tell us Joseph and Mary, much to the apparent chagrin and horror of catholicism, had other children.
I came across a collection of over 20 verse by verse commentaries at: https://www.studylight.org/commentary/matthew/12-46.html
The opinions on whether Mary had other children are many and diverse.
Some commentaries, e.g., Adam Clarke and Coffman, support your assertion that Joseph and Mary had other children. Others, e.g., Gill and Wesley, support the belief that the brothers and sisters were not Mary’s sons and daughters. Still others either do not address the question or assert that the question of who the brothers and sisters were cannot be answered with any degree of certainty.
As one looks at the various commentaries, it becomes clear that arguments in favor of Mary having other children and arguments against Mary having other children are equally weak. They are all conjectures based on assumptions. As Ellicott stated in his commentary, “The facts in the Gospel records are scanty.” There just is not sufficient contextual evidence from Scripture to solidly support either position.
Regarding your comment about the Trinity, take a look at the commentaries on Matthew 28:19, “Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost” The context is clear in this passage, and the commentaries are very much in agreement.
