τέκτων may be used to denote "mason" or "freemason" now, but it didn't back in Christ's time (or earlier). You should really find a good dictionary to help you out, one that lists the references. A τέκτων was a carpenter or worker in wood (joiner). In a few texts it's even used in opposition to a mason, who was a λιθολόγος (stone-worker). Occasionally it was used to generally denote a craftsman or workman, or a master in an art (like poetry, gymnastics, etc.). There are a number of related words used exclusively in ancient texts for carpentry-related things (woodshop, joiner, carpentry, etc.).
Actually, τέκτων is the foundation for the modern word 'architect'. (archi-tekton, meaning 'master-mason'). As you well know, a Master Mason is the title given to a 3rd degree Mason.
Yes, τέκτων is the foundation of "Architect," but that doesn't mean "Master Mason." It meant "Master builder" or "Master joiner."
You keep asserting that the word means what it doesn't. I think it's source time, my friend:
My analysis in the quoted text is a summary of what appears in "A Greek-English Lexicon" by Henry George Liddell and Robert Scott (1924 edition). It is supported by the entry in Georg Autenrieth's "Homeric Lexicon" (1889 edition), which says "maker, builder, joiner, carpenter."
If you'd like an easy app (at least for iPhone, not sure if it's available for Android), it's "Lexiphanes."
The Old Testament makes a distinction which parallels the use outside of scripture in the ancient world. It comes through in 4 Kings (or 2 Kings if you're using non-LXX nomenclature):
12:12 και εδωκαν το αργυριον το ετοιμασθεν επι χειρας ποιουντων τα εργα των επισκοπων οικου κυριου και εξεδοσαν τοις τεκτοσιν των ξυλων και τοις οικοδομοις τοις ποιουσιν εν οικω κυριου
12:13 και τοις τειχισταις και τοις λατομοις των λιθων του κτησασθαι ξυλα και λιθους λατομητους του κατασχειν το βεδεκ οικου κυριου εις παντα οσα εξωδιασθη επι τον οικον του κραταιωσαιhttp://bibledatabase.net/html/septuagint/12_012.htm
Here is the KJV, offset by one number in the verses:
11 And they gave the money, being told, into the hands of them that did the work, that had the oversight of the house of the Lord: and they laid it out to the carpenters and builders, that wrought upon the house of the Lord,
12 And to masons, and hewers of stone, and to buy timber and hewed stone to repair the breaches of the house of the Lord, and for all that was laid out for the house to repair it.http://www.biblegateway.com/passage/?search=+2+Kings+12%3A11-12&version=KJV;AKJV
