Chiswick Baptist Church is a (spoiler alert) Baptist Church located on Chiswick High Road (well almost... well, in Annandale Road, almost at its junction with Chiswick High Road). Its construction started in 1896, it has a nice tower and remarkable windows for a recent church. And those pretty red bricks of the late 1800s which are typical for the buildings designed and errected for the 19th-century bourgeoisie in Bedford Park and Chiswick as a whole. The same kind of bricks you will find on other churches in the area (check for the Church Micro Series traditional and multi-caches in Chiswick, there should be quite a few!)

At the coordinates of the multi, you won't find any cache but the clues needed to complete the first stage of the multi. To know how to gather the clues for stages 2 and 3 and how to calculate the final coordinates, please read the description of the 2 other waypoints / stages.
Stage 1 - (at the given coordinates for the multi). You should see a large blue board with white letters on the outside wall of the church. i) Let A be the number of letters in the first line of the board. ii) Find the third line from the bottom. How many letters are there in the first word of this line? Let this number be C. iii) Look at the phone number on the board. It is 07H33 478G18.
Stage 2, 3 and how to calculate the final coordinates: see description of the waypoints / stages. You can check if you calculate it the final GZ right by visiting geocheck.org. 
Have fun!
