Thayer’s Greek Lexicon
Greek Dictionaries / April 16, 2024

A classic Greek lexicon useful for every theology student. Note that Thayer was a universalist, so be careful with any word dealing with salvation, and also the Trinity (his definition of “Christ” would seem to doubt Jesus’ deity). Basically the majority of his word definitions are from standard usage in the Greek NT and classical literature, so in theologically charged words, be careful.

American Church Dictionary and Cyclopedia
Dictionaries / January 3, 2023

The American Church Dictionary and Cyclopedia By WIlliam James Miller First published in 1901. The Preface explains: “The writer of the following pages has long been convinced, from an experience of many years in the Ministry, that a great desideratum among Church people is a Church Dictionary, especially one not so expensive as the more costly works, and at the same time something more complete and satisfactory than a mere glossary of terms. What seems to be needed is an inexpensive, handy volume, “short enough for busy people, plain enough for common people, cheap enough for poor people,” yet complete enough to give the information needed. The present work was undertaken with this object in view.”
