GINOLJC, to all.
the topic of the OP is, "Is my salvation based upon my knowledge of the Trinity?", I have read many of the post here, and some, not all, are from half truth, which is a full lie in disguise, to down right misunderstanding. (which some just don't understand, but that's ok). to answer the topic question, NO. but, but do one need to know God the SAVIOUR, or lets be blunt here, ... JESUS .... YES. so having knowledge of the doctrine of the trinity is not prerequisite for salvation, but KNOWING the truth of who God is. for SALVATION is not based on a LIE, but TRUTH. so if the trinity concering who God is is TRUE, then your salvation is secure, because your "BELIEF" is based on TRUTH. for "BELIF" means, an acceptance that a statement is true or that something exists. so if the trinity is a statement TRUTH your salvation is TRUE.
the flip side is this, if the statement of the TRINITY is NOT "TRUE", then your SALVATION is based on a LIE, and then one's "BELIEF" is NOT TRUE. if One's beliefs in JESUS is not true, (based on a statement of a LIE), then one has no part in him, JESUS, the Saviour. for you "KNOW" him not, nor he know you. for salvation is based on "TRUTH in God the Saviour, Jesus the Christ. this is concering salvation. and SALVATION is based on the Foundation of TRUTH. a lie has no foundation, and so not TRUE.
once one has escaped, "SAVED", now one can add.
2 Peter 1:4 "Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
2 Peter 1:5 "And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;
2 Peter 1:6 "And to knowledge temperance; and to temperance patience; and to patience godliness;
2 Peter 1:7 "And to godliness brotherly kindness; and to brotherly kindness charity.
2 Peter 1:8 "For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.e
2 Peter 1:9 "But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.
2 Peter 1:10 "Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:
2 Peter 1:11 "For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ".
so if one get the FIRST thing right, "BELIEF" the truth, then one is sure, and grow in christ. so to KNOW JESUS in "TRUTH" is "sure".
